The Canadian one dollar coin, commonly called the Loonie, is a gold-coloured one-dollar coin introduced in 1987. It bears images of a common loon, a bird which is common and well known in Canada, on the reverse, and of Queen Elizabeth II on the obverse.
The coin's outline is an 11-sided curve of constant width. Its width of 26.5 mm and its 11-sidedness matched that of the already-circulating Susan B. Anthony dollar in the United States, and its thickness of 1.95 mm was a close match to the latter's 2.0 mm. Its gold colour differed from the silver-coloured Anthony dollar; however, the succeeding Sacagawea and Presidential dollars matched the loonie's overall hue. Other coins using a curve of constant width include the 7-sided British twenty pence and fifty pence coins (the latter of which has similar size and value to the loonie, but is silver in colour).
When introduced, loonie coins were made of Aureate, a bronze-electroplated nickel combination. Beginning in 2007, some loonie blanks also began to be produced with a cyanide-free brass plating process. In the spring of 2012, the composition switched to multi-ply brass-plated steel. As a result, the weight dropped from 7.00 to 6.27 grams. This has resulted in the 2012 loonie not being accepted in some vending machines. The Toronto Parking Authority estimates that at about $345 per machine, it will cost about $1 million to upgrade almost 3,000 machines to accept the new coins. The Mint states that multi-ply plated steel technology, already used in Canada's smaller coinage, produces an electromagnetic signature that is harder to counterfeit than that for regular alloy coins; also, using steel provides cost savings and avoids fluctuations in price or supply of nickel.
The coin has become the symbol of the Canadian dollar: media often discuss the rate at which the loonie is trading against other currencies. The nickname loonie (huard in French) became so widely recognized that in 2006 the Royal Canadian Mint secured the rights to it. When the Canadian two-dollar coin was introduced in 1996, it was in turn nicknamed the "toonie" (a portmanteau of "two" and "loonie").
Canada first minted a silver dollar coin in 1935 to celebrate the 25th anniversary of George V's reign as king. The voyageur dollar, so named because it featured an Indian and a French voyageur paddling a canoe on the reverse, was minted in silver until 1967, after which it was composed primarily of nickel. The coins did not see wide circulation, mainly due to their size and weight; the nickel version weighed 15.6 grams (0.55 oz) and was 32.1 millimetres (1.26 in) in diameter, and was itself smaller than the silver version.
By 1982, the Royal Canadian Mint had begun work on a new composition for the dollar coin that it hoped would lead to increased circulation. At the same time, vending machine operators and transit systems were lobbying the Government of Canada to replace the dollar banknotes with wider circulating coins. A Commons committee recommended in 1985 that the dollar bill be eliminated despite a lack of evidence that Canadians would support the move. The government argued that it would save between $175 and $250 million over 20 years by switching from bills that had a lifespan of less than a year to coins that would last two decades.
The government announced on March 25, 1986, that the new dollar coin would be launched the following year as a replacement for the dollar bill, which would be phased out. It was expected to cost $31.8 million to produce the first 300 million coins, but through seigniorage (the difference between the cost of production and the coin's value), expected to make up to $40 million a year on the coins. From the proceeds, a total of $60 million over five years was dedicated toward funding the 1988 Winter Olympics in Calgary.
The failure of the Susan B. Anthony dollar coin in the United States had been considered and it was believed Americans refused to support the coin due to its similarity to their quarter coin and its lack of esthetic appeal. In announcing the new Canadian dollar coin, the government stated it would be the same overall size as the Susan B. Anthony coin – slightly larger than a quarter – to allow for compatibility with American manufactured vending machines, but would be eleven sided and gold coloured.
It was planned that the coin would continue using the voyageur theme of its predecessor, however the master dies that had been struck in Ottawa were lost in transit en route to the Mint's facility at Winnipeg. A Commons committee struck to investigate the loss discovered that the Mint had no documented procedures for transport of master dies and that it had shipped them via a local courier in a bid to save $43.50. It was also found to be the third time that the Mint had master dies within five years. An internal review by the Royal Canadian Mint argued that while a policy existed to ship the obverse and reverse dies separately, the new coins dies were packaged separately but were part of the same shipment. The Mint also disagreed with the Royal Canadian Mounted Police's contention that the dies were simply lost in transit. It believed the dies were stolen. The dies were never recovered.
Fearing the possibility of counterfeiting, the government approved a new design for the reverse, replacing the voyageur with a Robert-Ralph Carmichael design of a common loon floating in water. The coin was immediately nicknamed the "loonie" across English Canada, and became known as a "huard", French for "loon", in Quebec. The loonie entered circulation on June 30, 1987, as 40 million coins were introduced into major cities across the country, though an error by the banks resulted in some Calgary residents receiving the coins one week earlier. Over 800 million loonies had been struck by the coin's 20th anniversary.
Two years after the loonie's introduction, the Bank of Canada ceased production of the dollar banknote as the final dollar bills were printed on June 30, 1989.

The lucky loonie 
In recent years, the golden-coloured loonie became associated with Canada's winning hockey and curling teams and has been viewed as a good-luck charm in international competition. The legend began during the 2002 Winter Olympics, when a Canadian icemaker for the ice surfaces in the ice hockey tournament, Trent Evans, buried a loonie under centre ice. The original reason for placing the loonie was to assist in the puck-drop: the centre ice at Salt Lake was emblazoned with a large logo, and was missing the customary circle used by the referee and face-off players as a target for the puck — so he needed to add some kind of a dot as a puck target that would not stand out, and a loonie buried under the ice served well. Both the Canadian men's and women's hockey teams won gold in the tournament, the men's 50 years to the day after their last gold medal victory. Following the Games, Team Canada executive director Wayne Gretzky recovered the coin and gave it to the Hockey Hall of Fame.
A loonie was also used at the IIHF World Hockey Championships between Canada and Sweden on May 11, 2003. This lucky loonie is known affectionately as the Helsinki Loonie. It was hidden surreptitiously before the Gold-Medal hockey game and saw Team Canada to victory. After forward Anson Carter scored against Swedish goaltender Mikael Tellqvist in overtime to win the World Hockey Championship for Canada, Team Canada officials admitted they had placed a Loonie in the padding beneath the crossbar of the Swedish net.
The legend is also prevalent in curling, as the Kevin Martin rink at the 2002 Winter Olympics had won silver medals on a sheet with silver-coloured quarters underneath the surface. At the 2006 Winter Olympics, the Canadian icemakers in the curling tournament buried two loonies, one at each end of the sheet — coincidentally, Brad Gushue would win the gold medal there. In the same Olympics, the icemakers at the hockey tournament announced that they would not bury a loonie under the ice. The men's team finished out of the medals while the women's team won gold. Likewise, for the 2010 Winter Olympics, as part of the venue construction for the curling venue, three loonies were placed in the floor by the architect before the concrete was poured. Both the Canadian men's and women's ice hockey teams took home gold.
This legend is kept alive by the Royal Canadian Mint, which has since issued specially-designed "Lucky Loonies" for each year the summer and winter Olympics Games are held. Two new Olympic-themed loonies are due to be released in commemoration of the 2010 Winter Olympics being held in Vancouver-Whistler.
Team Russia has also made use of the lucky loonie — in the 2008 IIHF World Championship in Quebec City Alexander Ovechkin famously dug out the "lucky loonie" from centre ice after Russia beat Canada 5–4 in overtime and gave it to Russian teammate Ilya Nikulin, who cut it in two and made two necklaces out of the souvenir.
An episode of Star Trek: Deep Space Nine ("Blaze of Glory") also made mention of a lucky loonie – although the episode's air date (May 12, 1997) predates the more-recent Olympic tradition, making it impossible for the scriptwriter to have intended a connection between the fictional coin and its real-world counterpart. The character, Michael Eddington, had a family heirloom in the form of a 22nd century Canadian one dollar coin that he called his "lucky loonie".
