A challenge coin is a small coin or medallion (usually military), bearing an organization’s insignia or emblem and carried by the organization’s members. Traditionally, they are given to prove membership when challenged and to enhance morale. In addition, they are also collected by service members. In practice, challenge coins are normally presented by unit commanders in recognition of special achievement by a member of the unit. They are also exchanged in recognition of visits to an organization.[1]


There are several stories detailing the origins of the challenge coin.

The Roman Empire rewarded soldiers by presenting them with coins to recognize their achievements.[2]

According to the most common story, challenge coins originated during World War I.[3][4] Before the entry of the United States into the war in 1917 American volunteers from all parts of the country filled the newly formed flying squadrons. Some were wealthy scions attending colleges such as Yale and Harvard who quit in mid-term to join the war.[5][6]

In one squadron, a wealthy lieutenant ordered medallions struck in solid bronze and presented them to his unit. One young pilot placed the medallion in a small leather pouch that he wore about his neck. Shortly after acquiring the medallion, the pilot's aircraft was severely damaged by ground fire. He was forced to land behind enemy lines and was immediately captured by a German patrol.[7] In order to discourage his escape, the Germans took all of his personal identification except for the small leather pouch around his neck. In the meantime, he was taken to a small French town near the front. Taking advantage of a bombardment that night, he escaped. However, he was without personal identification. He succeeded in avoiding German patrols by donning civilian attire and reached the front lines. With great difficulty, he crossed no-man's land. Eventually, he stumbled onto a French outpost. Saboteurs had plagued the French in the sector. They sometimes masqueraded as civilians and wore civilian clothes. Not recognizing the young pilot's American accent, the French thought him to be a saboteur and made ready to execute him. He had no identification to prove his allegiance, but he did have his leather pouch containing the medallion. He showed the medallion to his would-be executioners and one of his French captors recognized the squadron insignia on the medallion. They delayed his execution long enough for him to confirm his identity. Instead of shooting him they gave him a bottle of wine.[2][5][6][8]

Back at his squadron, it became tradition to ensure that all members carried their medallion or coin at all times.[2] This was accomplished through challenge in the following manner: a challenger would ask to see the medallion, if the challenged could not produce a medallion, they were required to buy a drink of choice for the member who challenged them. If the challenged member produced a medallion, then the challenging member was required to pay for the drink. This tradition continued throughout the war and for many years after the war while surviving members of the squadron were still alive.[6][8]

According to another story, challenge coins date back to World War II and were first used by Office of Strategic Service personnel who were deployed in Nazi held France. Similarly, Jim Harrington proposed a Jolly sixpence club amongst the junior officers of the 107th Infantry.[2] The coins were simply a local coin used as a "bona fides" during a personal meeting to help verify a person's identity. There would be specific aspects such as type of coin, date of the coin, etc. that were examined by each party. This helped prevent infiltration into the meeting by a spy who would have to have advance knowledge of the meeting time and place as well as what coin was to be presented, amongst other signals, as bona fides.

While a number of legends place the advent of challenge coins in the post-Korean Conflict era (some as late as the Vietnam War), or even later, Colonel William "Buffalo Bill" Quinn had coins made for those who served in his 17th Infantry Regiment during 1950 and 1951.

Colonel Verne Green, commander of the 10th Special Forces Group-A, embraced the idea. He had a special coin struck with the unit's crest and motto in 1969. Until the 1980s, his unit was the only unit with an active challenge coin tradition.[9][10][11]

There is another story about an American soldier scheduled to rendezvous with Philippine guerrillas during WWII. As the story goes, he carried a Philippine solid silver coin that was stamped on one side with the unit insignia. The coin was used to verify, to the guerrillas, that the soldier was their valid contact for the mission against the Japanese.

The challenge coin tradition has spread to other military units, in all branches of service, and even to non-military organizations as well as the United States Congress, which produces challenge coins for members of Congress to give to constituents. Today, challenge coins are given to members upon joining an organization, as an award to improve morale, and sold to commemorate special occasions or as fundraisers. In the Air Force, military training instructors award an airman's coin to new enlisted personnel upon completion of their United States Air Force Basic Military Training and to new officers upon completion of the Air Force Officer Training School.[8][12]

U.S. presidents[edit]

President Bill Clinton displayed several racks of challenge coins, which had been given to him by U.S. servicemembers, on the credenza behind his Oval Office desk. These coins are currently on display at the Clinton Library. The challenge coins appear in the background of his official portrait, now hanging in the White House.

President George W. Bush received a challenge coin from a Marine combat patrol unit during his short but unexpected visit to Al Asad Airbase in Anbar province, Iraq, 3 September 2007.[13]

President Barack Obama placed challenge coins on the memorials of the soldiers killed in the 2009 Fort Hood shooting.[14]


The tradition of a challenge is the most common way to ensure that members are carrying their unit's coin. The rules of a challenge are not always formalized for a unit, and may vary between organizations. The challenge only applies to those members that have been given a coin formally by their unit. This may lead to some controversy when challenges are initiated between members of different organizations and is not recommended[according to whom?]. The tradition of the coin challenge is meant to be a source of morale in a unit, and forcing the challenge can cause a reverse effect. The act of challenging is called a "Coin Check" and is usually loudly announced.[8][10][15]

The challenge, which can be made at any time, begins with the challenger drawing his/her coin, and slapping or placing the coin on the table or bar. In noisy environments, continuously rapping the challenge coin on a surface may initiate the challenge. (Accidentally dropping a challenge coin is considered to be a deliberate challenge to all present.) Everyone being challenged must immediately produce the coin for their organization and anyone failing to do so must buy a round of drinks for the challenger and everyone else who has their challenge coin. However, should everyone challenged be able to produce their coin, the challenger must buy a round of drinks for the group.[8][9][10]

While most holders of challenge coins usually carry them in their pockets or in some other readily accessible place on their persons, most versions of the rules permit a challenged person "a step and a reach" or if an individual has an extra coin to pass it off to the person closest to them. Coins on belt buckles or key chains are not acceptable for meeting a challenge. However, a coin worn around the neck is acceptable for meeting a coin challenge.[9][10][15]

Variants of the rules include, but are not limited to, the following: If someone is able to steal a challenge coin, everyone in the group must buy a drink for that person. During a challenge, everyone in the group must buy a drink for the holder of the highest-ranking[clarification needed] coin. A coin presented to a low rank, by a high rank, (i.e.: Admiral) trumps all low rank coins in a challenge. Traditionally, the presentation of a coin is passed during a handshake. Some units provide strict time limits to respond to a challenge.

Traditionally, rules of a challenge include a prohibition against defacing the coin, especially if it makes it easier to carry at all times. If the challenge coin is attached to a belt buckle or key ring, or has had a hole drilled in it to attach to a lanyard, it no longer qualifies as a challenge coin.[10][16] A safer place to carry a coin is in a pouch worn around the neck.


There are many finishes available—from a simple pewter to 24K gold. While there are only a few base metals, the patina (finish) can range from gold, silver, nickel, brass, copper. bronze plus the antiqued variations. Soft or hard enamel or a printed inset with an epoxy coating may add color (the epoxies are often more resilient and scratch resistant than the metal surfaces).[17]


Challenge coins are moderately inexpensive to design and produce. There are two basic processes by which to manufacture: zinc-alloy castings or die struck bronze.

Zinc alloy castings offer the advantage of low cost. While a die struck bronze or brass coin is more expensive, the result renders a far superior product (numismatic quality).

As of 2010, coins manufactured in China and South Korea typically cost between US$2.50 to US$7.00 per coin depending on production process and complexity of design, laser engraving, enamels, voids, etc. The dies must be sculpted by an artist and can range in cost from US$50 to US$300 depending on complexity. The cost of domestic manufacture can be many times this amount.

In order to be competitive, most North American companies offering challenge coins rely on having the product manufactured 'off-shore'. Many challenge coins are fabricated in South Korea, as the connection to the US military bases there is strong,[citation needed] and costs are cheaper than those made in the US.[citation needed]


Besides using coins for challenging, they are also used as rewards or awards for outstanding service or performance of duty. As such, they are used as a tool to build morale.[8][15] Military officials occasionally give them to non-military personnel for outstanding service or rewards, like the case of student athletes at Northeastern University.[18]

In the context as they are used by the modern U.S. military, the tradition probably began among special forces units during the Vietnam War.[citation needed] The tradition spread through the Airborne community, and by the early 1980s also into the 75th Ranger Regiment.[citation needed] As officers were reassigned as their careers progressed, they carried with them the tradition of awarding a unit coin for acts that were worthy of recognition, but yet lacked enough merit to submit the soldiers act for an official medal.[citation needed]

One widely known challenge coin in the United States Air Force was the "Bull Dog" challenge coin that was exclusive to B-52 enlisted tail gunners. Since the B-52 gunner position was phased out in 1991, this famous challenge coin has become rarer.

This coin was presented to gunners upon graduation from their Air Force technical training and their entry into the "Gunners Association". In the earlier days of bombers, a bean or a nugget was used. The coin represents the attributes of strength and courage as reflected in the Bulldog, the gunner's official mascot. The coin was also given to certain "honorary gunners", usually commanders and leaders who portrayed the spirit of the bulldog.

Some collectors buy them for their numismatic value.

Coins given as awards for accomplishments are normally given to the recipient during a handshake, passing from the right hand of the giver to the right hand of the awardee. It is also normal for the giver to offer a brief explanation of the reason for awarding the coin.

"Perhaps the largest collection of Army Engineer related coins exists in a large cabinet in the Army Engineer Association's (AEA) Engineer Regimental Store, located in the Engineer Museum at the home of the Engineer Regiment. These coins were donated by store customers who have passed through the store since it opened in the late 1980s."[19]

Popular culture[edit]

The coin must be earned by the members and can only be presented by a national officer or chapter president for a noteworthy accomplishment.[22]

Harley Owners Group[edit]

In 2009, the Harley Owners Group (HOG) created and made available its own challenge coin to Harley-Davidson motorcycle owners through the HOG members only website, stating: "Those who ride Harley-Davidson motorcycles share a bond in much the same way as those who have served their country with pride. Carrying a H.O.G. National Challenge Coin in your pocket, on your bike or off, is a meaningful way to show your pride of Harley-Davidson ownership—while also paying tribute to those who serve." The HOG National Challenge coin, measures 1.75 inches (44 mm) in diameter and is minted in US from solid brass alloy with an antique finish. The HOG eagle logo is stamped on the coin. The Harley-Davidson bar and shield logo encircled with the words "the official riding club of Harley-Davidson" is stamped on the back.[26]


In his audio commentary for the DVD release of Iron Man 2, film director Jon Favreau notes that he had Iron Man 2 challenge coins made to distribute to United States Air Force personnel as a gesture of thanks for their cooperation while the production (and its predecessor, Iron Man) filmed on location at Edwards Air Force Base.[27]

The crowdfunded movie Lazer Team gave challenge coins to its backers as an optional perk of funding the movie.[32]


One of the first appearance of a challenge coin within the Canadian Forces was that of the Canadian Airborne Regiment. Although conceptualized in the early 1970s, it was not officially adopted until the regiment returned from Cyprus in 1974.[33]

Recognized as an "Americanism", the widespread use of challenge coins is new to the Canadian Forces (CF) and was introduced by General Rick Hillier as the Canadian Army began to work closer with the US military. While many regiments and military establishments purchase them as 'challenge coins', most branches and schools within the CF use them for presentation purposes.

The first RCAF coin belonged to 427 Squadron. Back in the Second World War, 427 and the film studios Metro-Goldwyn-Mayer (MGM) shared the lion as their respective symbol. During a ceremony held on 27 May 1943, a bronze statuette of a Lion was presented to the Squadron as were MGM's coins for the Squadron members.[34] These coins granted free access to the MGM's theaters in Britain and were popular with aircrew and ground crew alike. In 1982, the custom was reintroduced by Lieutenant-Colonel Hugh Cunnigham, then the squadron commanding officer; it has since expanded widely within the RCAF Tactical Aviation community.[citation needed]

Every new officer cadet at the Royal Military College of Canada in Kingston, Ontario, is issued a challenge coin upon completion of First-Year Orientation Period. The coin is engraved with the name of the college in French and English surrounding the college's coat of arms on the obverse. The cadet's college number and the Memorial Arch is on the reverse surrounded by the motto in both languages.[citation needed]

Members of the Corps of Royal Canadian Electrical and Mechanical Engineers Fund are issued challenge coins with the current RCEME badge and the member's branch fund membership number on the obverse side, and the original pre-unification RCEME badge and branch motto on the reverse side. Usually, these are issued to craftsmen at the Canadian Forces School of Electrical and Mechanical Engineering, in Borden, Ontario, where branch fund membership is first offered.

The coin from Commander Canadian Special Operations Forces Command (CANSOFCOM) is a dull colour, but distinct by its pierced sections.

Many of the CF training centres and staff colleges have a unique coin—some available for the students to purchase, others available only by presentation by the establishment or the commandant for exemplary achievement while attending the facility. General Walter Natynczyk, when he was chief of the Defence Staff, and the Canadian Forces Chief Warrant Officer often present their personalized coins to deserving soldiers.

Police, security and fire departments have embraced the concept and have found coins to be an excellent means of team building and creating a sense of brotherhood or belonging. Many feature a patron saint, badge or representative equipment.


The challenge coin tradition was introduced into the Swiss Armed Forces by American officers on training missions and other assignments for the Organization for Security and Co-operation in Europe, of which Switzerland is a member. Coins are not issued, but rather ordered and paid for by Swiss officers of various branches within the Army.

Australia & New Zealand[edit]

Challenge coin of the Warrant Officer of the Air Force, Royal Australian Air Force; Specifically, WOFF-AF Mark Pentreath (7th WOFF-AF).

Coins have come into use by various Australian and New Zealand political leaders, senior officers and NCOs, under the influence of presentations from American personnel.[11] New Zealand challenge coins have been in existence since at least 1941.[35]


British military medical units discovered the tradition while working with American units in Iraq and Afghanistan. The Department of Military Anesthesia and Critical Care has been issuing a coin since 2006.[4] Northumbria Police's Firearms Support Unit introduced their Challenge Coin in 2017 after their close ties with numerous military units, notably the Royal Marines and the Dutch Marines.
