The Canadian Loonie dollar coin uses another Reuleaux polygon with 11 sides. Pike recounts his boyhood friendship with Ivan "Loonie" Loon. The same is true of the 11-sided loonie (Canadian dollar coin). The term "loonie" has since become synonymous with the Canadian dollar itself. In Canada, the one-dollar coin is known as the "loonie". When introduced, loonie coins were made of Aureate, a bronze-electroplated nickel combination. It was then replaced with the 1987 Canadian 1-dollar coin (colloquially known as the "loonie"). The lucky loonie quickly became a piece of Canadian lore. This would be followed by the Sterling Silver Lucky Loonie coins in 2004 and 2006. In 1987, the coin was replaced by the loonie. The $1 coin (the "loonie") was released in 1987. The Sandersons leave while Loonie flees back to Indonesia. One of them, Trent Evans, secretly placed a loonie at centre ice. The Terry Fox Loonie was unveiled in 2005 and designed by Senior Engraver Stanley Witten. This became known as the loonie.
