There was formerly some correspondence between the size of Canadian coins and British coins of similar value. For example, the large Canadian penny was identical in size and value to the contemporary British half-penny, which was in the Edward VII version, and slightly larger during Victoria's reign. Likewise, the Canadian quarter (23.81 mm diameter) was virtually identical in size and value to the British shilling – worth 12 British pence or about 24 Canadian cents, with a diameter. The Canadian 5¢ coins, until the larger nickel coins of 1922, were 15 mm silver coins quite different from the U.S. "Liberty head" nickels of 1883–1913, which were 21.2 mm and copper-nickel alloy, but more like the older U.S. half dimes.
