Apollo 15 postal covers incident
The Apollo 15 postal covers incident, a 1972 NASA scandal, involved the astronauts of Apollo 15, who carried about 400 unauthorized postal covers into space and to the Moon's surface on the lunar lander Falcon. Some of the envelopes were sold later at high prices by West German stamp dealer Hermann Sieger, and are known as "Sieger covers". The crew of Apollo 15, David Scott, Alfred Worden and James Irwin, agreed to take payments for carrying the covers; though they returned the money, they were reprimanded by NASA. Amid much press coverage of the incident, the astronauts were called upon to appear before a closed session of a Senate committee and never flew in space again.
The three astronauts and an acquaintance, Horst Eiermann, had agreed to have the covers made and taken into space. Each astronaut was to receive about $7,000. Scott arranged to have the covers postmarked on the morning of the Apollo 15 launch. They were packaged for space and brought to him as he prepared for liftoff. Apparently due to an error, they were not included on the list of the personal items he was taking into space. These covers spent from July 30 to August 2, 1971 on the Moon inside the Falcon. On August 7, the date of splashdown, the covers were postmarked again on the recovery carrier USS Okinawa. One hundred were sent to Eiermann (and passed on to Sieger); the remaining covers were divided among the astronauts.
Worden had made arrangements to carry 144 additional covers, largely for an acquaintance, F. Herrick Herrick. When NASA in late 1971 heard that the Herrick covers were being sold, the astronauts' supervisor, Director of Flight Crew Operations Deke Slayton, warned Worden to avoid further commercialization of what he had been allowed to take into space. After Slayton heard of the Sieger arrangement, he removed the three as backup crew members for Apollo 17, though the astronauts had by then refused compensation from Sieger and Eiermann. The Sieger matter became generally known in June 1972. There was widespread news coverage, with some saying astronauts should not be allowed to reap personal profits from NASA missions.
By 1977, all three former astronauts had left NASA. In 1983, they sued for the return of the covers impounded in 1972 and received them in an out-of-court settlement. One of the covers given to Sieger sold for over $50,000 in 2014.
After the start of the Space Age with the launch of Sputnik I on October 4, 1957, astrophilately (space-related stamp collecting) began. Nations such as the United States and USSR issued commemorative postage stamps depicting spacecraft and satellites. Astrophilately was most popular during the years of the Apollo Program's moon landings from 1969 to 1972.
Collectors and dealers sought philatelic souvenirs related to the American space flight program, often through specially-designed envelopes (known as covers). Cancelling them became a major duty of the employees of the Kennedy Space Center (KSC) post office on space mission launch days. Beginning in the late 1960s, Harold G. Collins, head of the Mission Support Office at KSC,[a] arranged for specially designed envelopes to be printed for the different missions, and to be cancelled on the launch dates. Such unflown philatelic covers were often gifts for the astronauts' friends, or for employees of NASA and its contractors. American astronauts were allowed to take Personal Preference Kits (PPKs) into space with them. These small bags, limited in size and weight, contained personal items the astronauts wanted to be flown as souvenirs of the mission. As the spaceflights moved toward and culminated in the moon landings, the public's fascination with items flown in space increased, as did their value.
Although it was not publicly known until September 1972, 15 of the men who entered space as Apollo Program astronauts, before Apollo 15, had agreed with a West German named Horst Eiermann to autograph 500 philatelic items (postcards and blocks of stamps) in exchange for $2,500. This included a member of each mission between Apollo 7 (1968) and Apollo 13 (1970). These items were not taken into space. Covers were prepared by the crews and flown on Apollo 11, Apollo 13 and Apollo 14. Ed Mitchell, Lunar Module Pilot for Apollo 14, took his to the Moon's surface in a PPK. These were often retained by the astronauts for many years; Apollo 11's Neil Armstrong kept his until he died, and they were not offered for sale until 2018.
The Apollo 15 mission began when the spacecraft blasted off from KSC on July 26, 1971, and ended when the astronauts and the Command Module Endeavour were recovered by the aircraft carrier USS Okinawa on August 7. Onboard Endeavour were Mission Commander David Scott, Command Module Pilot Alfred Worden and Lunar Module Pilot James Irwin. The Lunar Module Falcon, with Scott and Irwin aboard, landed on the Moon on July 30, 1971, and remained there for just under 67 hours. The mission set a number of space records and was the first to use the Lunar Rover. Scott and Irwin rode it to explore the area around the landing site during three periods of extravehicular activity (EVA). On August 2, before finishing the final EVA and entering the Lunar Module, Scott used a special postmarking device to cancel a first day cover of two stamps,[b] whose designs depicted lunar astronauts and a rover, commemorating the 10th anniversary of Americans entering space.[c]
Eiermann knew a stamp dealer named Hermann Sieger from Lorch, West Germany. The two had met by chance while on a bus to observe the launch of Apollo 12 in late 1969; Eiermann heard by Sieger's Swabian inflection that they were from the same part of Germany, and invited him to his house. Sieger got the idea for the lunar covers after hearing that the Apollo 12 astronauts had taken a Bible with them. When Sieger learned that Eiermann knew many astronauts, he proposed that an Apollo crew be persuaded to take covers to the Moon. Eiermann did not think astronauts would take money to do so, but agreed to ask them when Sieger characterized the payments as investments for the astronauts' children. Sieger's name was not mentioned in the approach to the astronauts.
Eiermann lived in Cocoa Beach, Florida, at the time of Apollo 15, and was a local representative of Los Angeles-based Dyna-Therm Corporation, which was a NASA contractor. According to Scott's autobiography, one night several months before launch, The astronaut’s supervisor, Director of Flight Crew Operations Deke Slayton had Scott and the other crew members come to dinner at Eiermann's house; Scott described Eiermann as a longtime friend of Slayton. Worden, in his autobiography, agreed that the crew was invited to dinner there, but described Scott as inviting his crewmates, and did not mention involvement by Slayton. In his testimony before a congressional committee in 1972, Scott described Eiermann as a "friend of ours", someone with whom he had dined and who knew many people at KSC, including a number of the astronauts. Scott also told the committee that he had met Eiermann at a party, rather than through another astronaut, and that the first Slayton knew of the space-flown Sieger covers was in April of 1972, following an inquiry from a member of the public.
At the dinner, Eiermann proposed the astronauts carry 100 special stamp covers, to be flown to the Moon. Worden stated that he and Irwin, who had not previously gone into space, were assured that this was common practice. The astronauts were told the covers would not be sold until some time in the future after the Apollo Program had ended. They would receive $7,000 each. They were informed that other Apollo crews had made and profited from similar agreements. Earlier astronauts had been given free life insurance. This benefit was no longer available by the time of Apollo 15. To ensure their families were provided for given the severe risks and dangers of their profession, the astronauts agreed to the deal, planning to put the payments aside as funds for their children. Scott earned $2,199 a month, Worden $1,715 and Irwin $2,235.
According to Scott, the astronauts also decided the covers would make good gifts and requested an additional 100 each for a total of 400 covers. Scott indicated in his testimony that after discussion with his crewmates, he expected the covers to be a "very private and noncommercial enterprise." He added: "I admit that this is wrong. I understand it very clearly now. But at the time, for some naive and thoughtless reason, I did not understand the significance of it." Irwin had concerns about the deal, but said nothing to avoid friction with his commander. He wrote in his autobiography that the initial meeting with Eiermann took place in May 1971, and that the astronauts met with him twice thereafter. Eiermann relayed instructions from Sieger on how to prepare the covers: they were to be postmarked twice, at KSC on the date of launch and on the recovery ship on the date of splashdown, and carry a signed statement from the astronauts with a certification from a notary. The certification would make the covers more sellable in Europe, where a notary is a legal professional who often verifies the document, not just the signatures.
An additional 144 covers were flown pursuant to an understanding between Worden and F. Herrick Herrick of Miami, a retired movie director and a stamp collector. According to a letter reporting on the stamp incident from NASA Administrator James C. Fletcher to the chairman of the Senate Committee on Aeronautical and Space Sciences, Clinton P. Anderson, Herrick was a friend of the three astronauts who had arranged for Worden, also a stamp collector, to buy an album full of stamps and proposed the astronauts take covers into space. These would be split and set aside for some years, and then sold. In his book Worden said he had been introduced to Herrick at lunch by former race car driver Jim Rathmann,[d] and that Herrick proposed the plan, with the space-flown covers to be divided between the two of them. Worden also related his insistence the covers must be held, unsold and unpublicized, until after the Apollo Program had ended, and he had retired from NASA and the Air Force. "I didn't want to do anything that would embarrass either myself or NASA, and I believed Herrick was as good as his word. It was a huge lapse in judgment on my part to trust this stranger. I was too old to believe in Santa Claus." In his 1972 testimony before the Senate committee, Worden described Herrick as a friend with whom he had had past dealings, and with whom he discussed the possibility of commemorative covers. According to a 1978 Justice Department report, before the Apollo 15 flight Herrick advised Worden that taking covers to the Moon would be a prudent investment because they would be valuable to stamp collectors.
While Scott and his crewmates were completing their mission training, a controversy developed within NASA and Congress over some of the souvenir silver medallions the crew of Apollo 14 had carried to the Moon. The private Franklin Mint, which had supplied the medallions, melted down some of those that had been flown. These were mixed with a large quantity of other metal, and commemorative medals were struck from the mass. These were used as a premium to attract people to pay to join the Franklin Mint Collector's Club. The fact that some part of the medals had flown to the Moon was used in the mint's advertisements. Because the Apollo 14 crew had accepted no money, they were not disciplined. Director of Flight Crew Operations Deke Slayton, who supervised the astronauts, reduced the number of medallions each member of Apollo 15 could take along by half. Slayton warned the Apollo 15 crew against carrying any items into space that could make money for them or others. In August 1965, Slayton had issued regulations requiring that items astronauts planned to carry be listed, approved, and checked for safety in space if similar items had not already been flown. Each crew member was bound by NASA standards of conduct issued in 1967 forbidding using one's position to make money for oneself or another person.
Creation and spaceflight
Eiermann was supposed to create the cachet for the special covers he had proposed, but time ran short and Scott did it instead. He used the Apollo 15 mission patch to create the design, and gave it to Collins of the Mission Support Office. Collins arranged with the Brevard Printing Company of Cocoa, Florida, for the design to be reproduced on both regular and lightweight envelopes. The company performed the work and billed Alvin B. Bishop Jr. $156 for the lightweight envelopes and $209 for the regular ones. Bishop, a public relations executive who specialized in the aerospace industry, and knew many astronauts, created specially designed covers for a number of the Apollo missions, which he supplied only to the crew and their families. He was at the time employed by Hughes Enterprises in Las Vegas; the company paid the bill.
Herrick arranged for a commercial artist with whom Worden discussed the design, resulting in 100 envelopes depicting the phases of the Moon. He listed these covers as part of the contents of his PPK for Slayton's approval, along with 44 first day covers that he owned. Ad-Pro Graphics, Inc. of Miami printed the Herrick envelopes, along with card inserts stating the accompanying cover had been carried on Apollo 15. Herrick paid the firm's bill of $50.50; he also obtained the postage stamps for the covers, and two rubber stamps stating the dates of the launch and splashdown. The design was printed on labels that were affixed to the envelopes. Not all Herrick covers are identical as different cachets, rubber stamp impressions and combinations of postage stamps were used. Worden also carried a cover honoring the Wright Brothers. Irwin carried 97 covers, one with a "flown-to-the-Moon" theme, eight with an Apollo 15 design, and 87 covers honoring Apollo 12, carried as a favor for Barbara Gordon, wife of Apollo 12 astronaut Dick Gordon. Barbara Gordon, a stamp collector, had wanted her husband to take the covers on his lunar mission, but he had refused. The flown-to-the-moon cover was a favor for a friend of Astronaut Gordon. Apollo 15 carried the cover from the Postal Service to be cancelled on the surface of the Moon. The agency also sent a backup, stowed in the Command Module with another cancellation device,[e] for use on the homeward journey if Scott did not get to postmark the lunar cover.
All covers except the group of 400 had been approved by Slayton, who stated in his testimony that he would almost certainly have approved them if asked, (assuming their weight could be negotiated with the Flight Director) on condition they remained in the Command Module and did not go to the lunar surface. In July 1972, after the story broke, William Hines of the Chicago Sun-Times wrote that "the idea that this complicated caper could have been carried out without the knowledge and at least tacit permission of Slayton is regarded by people familiar with NASA as ludicrous. Slayton's tight rein over his sometimes fractious charges is legendary."
The crew bought several hundred of the ten-cent First Man on the Moon postage stamp issue.[f] These were affixed to the lightweight envelopes by secretaries in the Astronaut Office. Collins had made arrangements with the KSC post office for it to open at 1:00 am on launch day—opening this facility so early on an Apollo launch morning was not unusual—and brought several hundred of the stamped covers. Once the envelopes had been run through the cancellation machine, he took them to the astronaut quarters, where members of the Flight Crew Support Team vacuum sealed them in teflon-covered fiberglass to fireproof them for space. Normally, if the Flight Crew Support Team found that an item was not on an astronaut's PPK list, they would add it, but team leader James L. Smotherman stated that "I goofed", explaining that he had confused the 400 covers with the Herrick envelopes, which had been approved by Slayton. Since the 400 covers had not been approved by Slayton, they were considered unauthorized. Scott stated, "I never intended to bootleg the covers. If I had intended to bootleg the covers, I certainly would not have allowed Mr. Collins to handle them or the rest of the people to assist me." Like other items being placed in the pockets on Scott's space suit (for example, his sunglasses), they were first shown to him by the suit technicians helping him dress. Divided into two packets, the bundled covers were about 2 inches (51 mm) thick and weighed about 30 ounces (850 g); they entered the spacecraft in Scott's pocket. Apollo 15 blasted off for the Moon at 9:34 am on July 26, 1971, with three astronauts and about 641 covers aboard.
At some point while the mission was en route to the Moon, the 400 covers were moved into the lunar lander Falcon; in his testimony, Scott agreed this violated the rules. He stated he did not recall how the transfer took place, and that he was only certain that the envelopes went to the lunar surface because they were in the bag of items taken out of the Falcon in preparation for the return to Earth. Worden stated in his testimony that they were aware of the presence of the covers in the Command Module after the mission's launch, but he did not recall if the covers had been among the many items moved into the Falcon in preparation for the lunar landing; he did not believe the matter had been discussed during the flight. He wrote in his autobiography that the night he had agreed to the deal with Eiermann "was the last I heard or thought of about the covers until after the flight ... What arrangements Dave [Scott], Eiermann, and Sieger made to get the covers onto the flight, I never knew until later. Dave later told a congressional committee that he had placed them in a pocket of his spacesuit, but he never shared that information with me". He indicated that the covers he had arranged to have on board, including those from Herrick, remained in his PPK in the Command Module throughout the flight. The testimony before Congress, from multiple individuals including Apollo 15 astronauts, was that carrying the covers did not interfere with the mission in any way.
[Worden:] Good. Very good.
[Worden:] Yes. You got to – yes. We've already signed those, haven't we? We haven't signed these? It really doesn't make much difference, does it?
[Worden:] We don't really have to sign them now I guess. We can do that anytime.
[Worden (continuing):] Yes, those – those covers would have been infinitely more valuable, I think.
[Scott:] Oh, well.
[Worden:] Maybe, Dave, it's just as well we didn't.
NASA, Apollo 15 Command Module Onboard Voice Transcription, p. 267. August 3, 1971, 1:56:11 pm through 1:57:21 pm EDT (mission time 196:22:11 through 196:23:21), aboard Endeavour in lunar orbit above the far side of the Moon
Apollo 15 splashed down about 335 miles (539 km) north of Honolulu at 4:46 pm EDT on August 7, 1971; the crew was retrieved by helicopters from the Okinawa. Scott had asked that a supply of the twin space stamps of the design he had cancelled on the Moon (issued August 2) be available on the Okinawa, and on July 14, Forrest J. Rhodes, who ran the postal facility at KSC wrote to the Chief Petty Officer in charge of the Okinawa's post office. The ship replied on the 20th, saying the stamps could be obtained in time. The stamps were secured from the post office at Pearl Harbor: 4,000 were flown to the Okinawa at sea by helicopter, reportedly in the custody of a naval officer joining the vessel. The astronauts had no money with them; their purchases were paid for by high-ranking officers aboard the Okinawa, who were later reimbursed. The crew had the assistance of Okinawa crew members in affixing the stamps for cancellation by the ship's post office. The Irwin covers were not postmarked, either at liftoff or splashdown. Worden wrote in his book that he never saw the covers Scott had brought until the astronauts were on the flight to Houston. However, as Scott mentioned he was having them postmarked with the splashdown date, Worden arranged to have that done for the ones he had taken into space. On the flight, the 400 covers were autographed and divided by the three astronauts. Irwin remembered the signing took several hours.
Distribution and scandal
On August 31, 1971, C.G. Carsey, a clerk in the Astronaut Office in Houston, typed certifications on 100 of the covers, with the aid of other NASA employees in her office. The certifications stated the cover had been on the Moon aboard the Falcon. The covers already carried a handwritten statement signed by Scott and Irwin that they had been landed on the Moon on July 30. Carsey later stated that in signing the certifications as a Texas notary public, she only intended to certify their signatures were genuine. The question of whether Carsey had improperly certified that the covers had been landed on the Moon (something she had no personal knowledge of) was the subject of an investigation by the Texas Attorney General. With the notary certifications, the last of Sieger's requirement for the covers was fulfilled. On September 2, Scott sent the 100 covers by registered mail to Eiermann who was in Stuttgart where he had moved. Eiermann turned the covers over to Sieger, and was rewarded with a commission of about $15,000—ten percent of the anticipated proceeds. One of Irwin's covers was given to Rhodes and one to the president of the Kennedy Space Center Philatelic Society; Irwin said in 1972 that he had retained the other six.
Sieger offered the covers to his customers, selling them at DM 4,850 (about $1,500 at the time), with a discount to those who bought more than one. He kept one for himself, and by November had sold the remaining 99. He numbered and signed the backs of the envelopes in the lower left as a token of their genuineness.
Worden recalled in his book that he sent the agreed number of 44 covers to Herrick soon after returning from space. He then sent him 60 belonging to himself for safekeeping. He also gave 28 to friends. Herrick consigned 70 covers to Robert E. Siegel, a prominent New York dealer. Siegel sold ten covers for a total of $7,900, receiving a commission from Herrick of 25 percent. Herrick sold three himself, at a price of $1,250 and placed several on commission in Europe.
In late October 1971, a potential customer for one of the Herrick covers wrote to NASA to inquire about its authenticity. On November 5, Slayton responded, saying NASA could not confirm whether it was genuine. He warned Worden to ensure that his covers would not be further commercialized. Worden wrote an angry letter to Herrick. In June 1972, Herrick instructed Siegel to send 60 covers to Worden in Houston, which he did by registered mail. Until this point, Siegel had assumed the 60 covers belonged to Herrick.
Probably before they made an official NASA trip to Europe in November 1971, the Apollo 15 astronauts received and completed the paperwork necessary to open accounts in a Stuttgart-area bank to receive the agreed $7,000 payments. According to Scott's testimony, while they were in Europe, they heard the Sieger covers were being sold commercially. Scott called Eiermann, who promised to look into it. The astronauts indicated they received the bankbooks in early 1972. Irwin remembered in his autobiography that before their trip to Europe, Scott came to him and said, "Jim, we are in trouble now—they are starting to sell the envelopes over there", and that the covers cast a shadow over their European trip. Scott said the crew discussed it among themselves, then decided that the receipt of funds was improper. In late February they returned the bankbooks to Eiermann, who responded that the astronauts should receive something for their efforts. The crew initially agreed to accept albums filled with aerospace-themed stamps for their children, including issues in honor of Apollo 15. Scott related, they decided that too was improper and said they wanted nothing. This final refusal happened in April 1972. Worden remembered, "we did this before NASA asked us anything about a deal with Sieger—before NASA even knew about it".
On March 11, 1972, Lester Winick, president of a group of collectors of space stamps and covers known as the Space Topics Study Group, sent a letter to NASA's general counsel asking a number of questions about the Sieger covers. The letter was forwarded for a response to Slayton, who casually mentioned it to Irwin in late March; Irwin told him to talk to Scott. Slayton spoke with Worden on the assumption that the covers referred to were among the group of 144, but Worden told him this was not necessarily the case and that he should talk to Scott. Slayton did talk to Scott in mid-April, just before the launch of Apollo 16. Scott told him there had been 400 covers not on the approved list, and that 100 had been given to a friend. In his autobiography, Slayton wrote that he confronted Scott and Worden about what he called a "regular goddamn scandal" just before the liftoff of Apollo 16. "[T]hey told me what the deal was, and I got pretty goddamn angry. So I was through with Scott, Worden, and Irwin. After 16 splashed down, I kicked them off the backup crew for 17." One reason for Slayton's anger was that he had defended the astronauts as rumors of the high prices being paid for the covers circulated; according to Andrew Chaikin in his history of the Apollo Program, Slayton "went out on a limb to defend his people". Slayton wrote to Winick, stating that the spacecraft had carried covers, but NASA could not confirm these particular envelopes had been taken; he did not tell Winick unauthorized covers had been flown. He sent a copy of his response to the general counsel's office at NASA Headquarters in Washington, which took no action. Slayton did not inform Administrator Fletcher, Deputy Administrator George M. Low or his own superior, Christopher C. Kraft of the postage stamp incident or of the disciplinary action he had taken[g]
In early June 1972, Low heard from a member of his staff of the possibility covers flown on Apollo 15 might have been sold in Europe. He asked Associate Administrator Dale D. Myers to enquire through NASA management channels for information. Low kept Fletcher informed of the situation as it developed. Myers made an interim report to Low on the 16th. Before he could make his final report on the 26th, the story broke with an article in The Washington Sunday Star on June 18. Kraft interviewed Scott on the 23rd. Low ordered a full investigation by NASA's Inspections Division on June 29. On July 10, the three astronauts were reprimanded for poor judgment, something that made it extremely unlikely that they would be selected to fly in space again. Richard S. Lewis, in his early history of the Apollo Program, noted that "in the atmosphere of wheeling and dealing that has characterized government agency-industrial contractor relations in the Space Age, the unauthorized freight that the Apollo 15 crew hauled to the moon was a boyish prank. In the rhetoric of space program critics, though, it was branded as exploitation for personal gain of the most costly technological development in history. In the press, the astronauts were treated like fallen angels." Scott, while stating, "we made a mistake in even considering it", felt that the reaction "was turning into a witch-hunt". Worden, though admitting blame for entering into the deal, felt that NASA had not adequately supported him, nor had Scott taken full responsibility for his role. Irwin, who would become an evangelist after leaving the Astronaut Corps, said that NASA had no choice but to reprimand them. He hoped he could turn the experience to use in his ministry, helping him empathize with others who had erred.
Another story that broke in mid-July was the dispute over the sculpture Fallen Astronaut, left on the Moon by Scott in tribute to those killed in the American and Soviet space programs; the sculptor was having copies made for public sale, over the astronauts' objection. Having read of these things in the newspapers, and concerned about the appearance of commercialization of Apollo 15, the Senate Committee on Aeronautical and Space Sciences set a hearing for August 3. It called a number of NASA employees including the astronauts, Slayton, Fletcher and Low to appear before it. Worden remembered that while there were difficult questions asked about the astronauts' conduct, part of the committee's concern was why NASA management had allowed another incident to happen so quickly after the Apollo 14 Franklin Mint matter. Members also wanted to know how it was that NASA's chain of command permitted allegations against the astronauts to go unreported to senior management. Invoking a rarely used Senate rule for when testimony might impact the reputation of witnesses or others, Senator Anderson had the meeting closed to the public.
Andrew Chaikin, A Man on the Moon: The Voyages of the Apollo Astronauts (1998 edition), pp. 497–498
None of the Apollo 15 crew ever flew in space again. Although there were few flights available as the Apollo Program wound down, Scott had aspired to command the American portion of the Apollo-Soyuz Test Project, the first joint mission with the Soviet Union. He was made a technical adviser on that mission instead and retired from the Air Force in 1975. He then became director of NASA's Dryden Flight Research Center, retiring from NASA in October 1977 and entering the private sector. Worden transferred to NASA's Ames Research Center in California, remaining there until his 1975 retirement both from the Air Force and NASA, and then entered the private sector. Irwin retired in 1972 and founded an evangelical group. The covers affair resulted in prejudice in the Air Force against former astronauts (all three Apollo 15 astronauts had served there). This deterred Apollo 14's Stu Roosa from returning to the Air Force when he left NASA, leading him to go into business instead. Although Apollo 16's Charles Duke had taken covers to the lunar surface in April 1972, changes to the PPK procedures instituted by NASA meant that none were taken on Apollo 17 that December. Today, astronauts are forbidden by federal regulation from taking philatelic items into space as mementoes.
The remaining covers in the astronauts' control (298 from the group of 400[h] and 61 more from Worden) were held by NASA amid the investigation; Worden said he surrendered them at Kraft's request on the understanding they would be returned once the investigation was over, but the covers were transferred to the National Archives in August 1973. There was a Justice Department investigation into the covers. Its Criminal Division decided in 1974 that no prosecution was warranted, but the Civil Division the following year assumed the covers would be retained by the government. In 1978 the department issued a report indicating that while the government might have some claim to the Herrick covers, it probably did not to the others, and in 1979 informed NASA that it had concluded that the government would likely lose if the astronauts sued for the covers. There was opposition among senators to the covers being returned, and in February 1980 a resolution passed the Senate that the government should keep the covers because of the commercialization. It died in the House of Representatives. In 1983, Worden sued, and the government agreed to return all the covers to the three astronauts.. The government felt it could not successfully defend the lawsuit, and that NASA either authorized the covers to be flown or was aware of them.
An Apollo 15 postal stamped cover that was one of the group of 298 impounded by the government sold at the January 2008 Novaspace auction for US$15,000. A Sieger cover sold in 2014 for over $55,000—the auctioneer noted that it was one of only four Sieger covers to come to public sale since the initial distribution. Worden sold many of the returned Herrick covers to pay debts from his unsuccessful 1982 run for Congress. When asked in 2011 where the covers were, he said, "Lord only knows. Some of them sold, some of them are still in a safety deposit box. They're probably all over the world by now." In a 2013 interview with Worden, Slate magazine found that "he’s vexed by lingering inaccuracies in the Wikipedia entry about the incidents. We ask: Why didn’t he get a friend to log in and correct the entries? He responds with a startled pause. 'Is that right? I didn't know you could do that!' "
