The Big Nickel is a nine-metre (30 ft) replica of a 1951 Canadian nickel, located at the grounds of Dynamic Earth in Sudbury, Ontario, Canada. The twelve-sided nickel is located on a small hill overlooking the intersection of Municipal Road 55 and Big Nickel Drive at the westernmost end of the Gatchell neighbourhood.
The idea for the Big Nickel began in 1963 when Ted Szilva, at the time a 28-year-old City of Sudbury fireman, read about a contest in the Sudbury Star. The contest, sponsored by the Sudbury Canada Centennial Committee, chaired by Maurice Lacourciere, requested that citizens of Sudbury forward suggestions on how they would like to see the City of Sudbury celebrate the Canadian Centennial. Among the many entries, Szilva put forward the suggestion for a major tourist attraction featuring a giant replica of a five-cent coin, an underground mine and a mining science centre. Szilva’s idea was rejected because the committee felt that "it did not have sufficient use for the citizens of Sudbury as such".
By this time, Szilva had independently researched his idea, and had concluded that it could indeed be a very viable and worthwhile project. He began to make this dream a reality by scouting out all of the highest hills in Sudbury to find the best location. On December 11, 1963, he purchased 17.5 acres (7.1 ha) of land from Walter Holdich for $1,000.00 with a $25.00 down payment. The land was ideal because of its unique location just between Sudbury and Copper Cliff. From the west, the large, rocky mountain provided a sensational view of the INCO mining and smelting complex, including the nightly slag dump, while from the east one had a beautiful view of the city of Sudbury.
After the land was acquired, the city refused to give Szilva the building permit for the nickel or a road allowance for access to the landlocked property, so he visited the president of INCO, John Pigott, and requested a lease for 4 acres (1.6 ha) of adjacent INCO land in Copper Cliff. This acquisition would ensure that Szilva would have access to his land. The land was leased for 99 years at $1.00 per year. Eventually he bought the leased land from INCO, in addition to another 15 acres (61,000 m2). Szilva contracted a firm to build the Big Nickel road, and Pioneer Construction paved the new road. The Big Nickel was eventually built on the crest of the hill, exactly three feet outside of the city of Sudbury limits in Copper Cliff, which did not require a building permit.
Fund raising 
Not yet financially secure, Szilva needed investors in order to make the dream a reality. Three men from Sudbury indicated that they would invest, but when the time came, they refused to put any money into Szilva’s new company, Nickel Monument Development Ltd.
Szilva eventually owned 99.9% of the shares of the company. In order to raise the money for the development of the project, Szilva had a series of commemorative coins struck which represented each of the monuments to be erected at the park. To have worldwide appeal, he conceived the idea for a numismatic park and called it the Canadian Centennial Numismatic Park. The Big Nickel would be its centrepiece. The uniqueness of this park is what appealed to the numismatists around the world. They purchased the medallions in order to support the construction and development of the park.
One such medallion package, mailed out to purchasers in 1964 from Nickel Monument Development contained three coins and a descriptive project brochure. Two of the coins were identical silver dollar sized .999 silver content Kennedy commemorative coins. The third was a silver dollar sized copper-coloured Kennedy commemorative coin. All three coins were identically marked on the obverse with a Kennedy profile above the words 'In God We Trust, 1964' surrounded by 'Canadian Centennial Numismatic Park, Sudbury, Canada'. On the reverse, each was marked with an eternal flame above the words 'And so let the word go forth that the torch has been lit,' and the words 'John Fitzgerald Kennedy 1917.1963'. The brochure discussed the medallions, the park ('Canada's Most Unique Tourist Attraction—Canadian Centennial Numismatic Park'), other fundraising ideas and planned future attractions.
In December 1963 Szilva had earned enough funds through mail-order sales to proceed with the first phase of the proposed development. He chose the 1951 five-cent piece and “coined” the phrase "The Big Nickel". Artist Steve Trenka designed the 1951 five-cent piece. His rendition of a nickel refinery was not based on any actual complex, though some believed it to be the INCO refinery in Sudbury. In 1951 the INCO smelter had three stacks, not one (unlike the five-cent piece) and the Inco Superstack which supposedly appeared in the centre of the buildings, was not erected until 1971. It would seem that The Big Nickel was the cause of these rumours, because of the similarity of its design to the five-cent coin and its proximity to the INCO complex.
The 1951 design was chosen for the Big Nickel since it marked the bicentennial of the chemical isolation of nickel by the Swedish chemist Baron Axel Frederic Cronstedt. This metal, of course, played a large role in the establishment of Sudbury as a mining town.
Before 1751, the element now known as nickel played havoc with refiners. Thought to be an alloy of copper, German miners coined the term, “Kupfernickel” or “Old Nick’s Copper”. This “Devil’s Copper” could not be extracted with the technology of the time. Cronstedt, however, was able to prove that the trouble refiners faced was due to an unknown element which he named nickel.
Szilva ultimately chose the 1951 Canadian nickel, minted by the Canadian Mint in 1951, to commemorate the 200th anniversary of the isolation of nickel as a metal, to show where Sudbury’s wealth came from, and to be a lasting tribute to the men and women who mined and processed the minerals in the Sudbury Basin. In short, the nickel was intended to exhibit Sudbury’s pride to the whole world.
Design and construction 
Bruno Cavallo, a local sign manufacturer and artist, also had an idea of constructing a five-cent coin out of chromium. He contacted Szilva, and the two proceeded with the construction of the 1951 nickel. It was to be built out of stainless steel, which Szilva suggested so it would endure the harsh Sudbury elements. Cavallo spent several months forming the artistic work. The first step was to project the image of the 1951 five-cent piece against a large wall at the Sudbury Steelworkers Hall. After projecting the image, it was traced by Szilva and Cavallo over a period of two nights onto large, thick pieces of brown paper. The traced sections were then transported to Cavallo’s shop where he handcrafted the numerous steel sheets from a wooden mould. The individual parts were then fastened to a moulded girdle structure and welded together with silver solder.
Szilva worked with Jim Nemis, whose company Noront Steel was contracted to engineer, fabricate and install the framework of the Big Nickel. The large stainless steel panels were fabricated by Dalite Corporation of Toronto and shipped to the Big Nickel site in May 1964. When completed, the Big Nickel was 30 feet (9.1 m) high and 24 inches (610 mm) thin.
The artistic work such as the design of the King George VI head, the numerals, maple leaf and the refinery were contracted to Cavallo Signs. All artistic work was affixed to the stainless steel panels on site.
The base, which was 12 feet high, 12 feet wide and 5 feet thick (3.7 m × 3.7 m × 1.5 m), was constructed by the Maple Leaf Masonry Company of Sudbury. It was made of various ore bearing rocks, field stone, and minerals mined in the Sudbury Basin in order to indicate the source of wealth in the Sudbury area. Upon its completion in 1964, the total cost of the construction of the Big Nickel was approximately $35,000.
On July 27, 1964, the park was officially opened. Szilva was extremely pleased that John Fisher, the Canadian Centennial commissioner, accepted his invitation to come to Sudbury that day to unveil the impressive Big Nickel Monument to a crowd of 1,500 family, friends, dignitaries and local residents. There was extensive media coverage of the event by The Sudbury Star, Canadian Coin News, and other Canadian publications as well as television coverage. This monumental day marked both the culmination of many months of planning, and the beginning of an era, which would see The Big Nickel develop into a world-renowned landmark, and Sudbury into a tourist centre in the north.
In an attempt to market the park as a world class tourist attraction, Szilva co-operated with the Sudbury Jaycees under president Allan Barnard in Sudbury in entering a float into the November 28, 1964 Grey Cup Parade with a replica of the monument along with the newly crowned Miss Big Nickel.
The underground model mine was tunnelled and built in 1965 by J.C. MacIsaac, of MacIsaac Mining and Tunnelling Co., and was expanded by the same company in 1969. Not only was the underground mine visited by over 100,000 people every year, but the mine represented the first time in Canadian history that a private enterprise and an educational institution, Cambrian College, would collaborate in order to provide on-site practical training in all facets of mining for students.
The park was always expanding and adding new features. Some of these features included helicopter rides, a train which ran around the circumference of the park carrying 55 passengers, a carousel, the famous “jail”, moon module, and informative film. Articles and pictures featuring the Big Nickel appear in hundreds of books, and it is recognized as an international landmark.
The Big Nickel, as the world’s only numismatic coin park, also featured coin monuments other than the 1951 nickel. Some of these coin monuments were the $20 gold coin monument (featuring Arms of Canada), the Kennedy half-dollar coin memorial (featuring an eternal flame), the fantasy copper (Canadian one cent 1965) penny, and the Lincoln coin memorial (1965 American penny) and a Canadian dime, there is no public record of the dismantling or current location of these other numismatic monuments, though pictures still exist. Mayor Joe Fabbro dedicated the wampum monument and Brotherhood of Man Memorial in May 1975. This memorial symbolized the early money traded by Canada's Aboriginal peoples and European settlers.
Municipality of Sudbury to proceed with the development of a major tourist attraction, as the government was willing to grant the funds to non-profit organizations. Szilva sold the Big Nickel to the Regional Municipality of Sudbury for $550,000, and the Sudbury Science Centre, later to be named Science North, was founded.
Dynamic Earth 
On January 22, 2001, the Big Nickel was dismantled for refurbishing of both the coin and the facility. Once refurbished, the coin was installed on the grounds of Science North, and the original Big Nickel site was redesigned into the Dynamic Earth facility. On May 10, 2003, the coin was moved back to a plain kickstand on the Dynamic Earth grounds, the stones of the original pedestal were simply discarded.
