| Nickel (Canadian coin) ： ウィキペディア英語版 |
The Canadian five-cent coin, commonly called a nickel, is a coin worth five cents or one-twentieth of a Canadian dollar. It was patterned on the corresponding coin in the neighbouring United States. Starting 4 February 2013, after the elimination of the penny, it became the smallest valued coin in the currency.The denomination (i.e., the Canadian five-cent piece) had been introduced in 1858 as a small, thin sterling silver coin, that was colloquially known as a "fish scale," not a nickel. The larger base metal version made of nickel, and called a "nickel," was introduced as a Canadian coin in 1922, originally as 99.9% nickel metal. These coins were magnetic, due to the high nickel content. Versions during World War II were minted in copper-zinc, then chrome and nickel-plated steel, and finally returned again to nickel, at the end of the war. A plated steel version was again made 1951–54 during the Korean War. Rising nickel prices eventually caused another switch to cupronickel in 1982 (an alloy similar to the U.S. nickel), but more recently, Canadian nickels are minted in nickel-plated steel, containing a small amount of copper.From 1942 to 1963, Canadian five-cent coins were produced in a distinctive 12-sided shape, evocative of the British threepence coin. Originally this was done to distinguish the copper-colored tombac (copper-zinc alloy) coins, from pennies. However, the characteristic shape was retained for another nine years after 1944 when this coin was later produced in 99.9% nickel and chrome-plated steel.The coin is produced by the Royal Canadian Mint at its facility in Winnipeg.==History==The first ever Canadian five-cent coins were struck by the Royal Mint in London as part of the introductory 1858 coinage of the Province of Canada. The coins were the same size and general composition as the corresponding American coins of the time, so the five-cent coin was based on the half dime. Although the American denomination was introduced as a larger copper-nickel coin in 1866, and the five-cent silver was retired in 1873, the Canadian five-cent coins remained small and silver until 1922.All Canadian coins (including five-cent coins) were struck in England at the Royal Mint (no mint mark) and the Birmingham Mint (H mint mark) until 1908, when the Ottawa branch of the Royal Mint opened. With the exception of some 1968 dimes struck at the Philadelphia Mint, all Canadian coins since 1908 have been minted in Canada.Due to a rise in the price of silver, Canadian coinage was debased from sterling silver (925 fine) to 800 fine in 1920. In 1922, silver was removed entirely from the five-cent coin, replacing it with a coin of roughly the same dimensions and mass as the American nickel. However, unlike the American coin, which was 75% copper and 25% nickel, the Canadian coin was pure nickel, as Canada was the world's largest producer of the metal. This coin has since been known almost universally as the nickel.The five-cent coin of Newfoundland, on the other hand, remained silver until the end of the Newfoundland coinage in 1947.The nickel's composition has changed several times, most notably during World War II and the Korean War when nickel was redirected to the war effort, where it was essential for armor production. In the latter part of 1942 and throughout 1943, the coins were minted in tombac, an 88% copper-12% zinc alloy that got its name originally from the Indonesian/Javanese word for brass or copper. In 1944 and 1945, and again from mid-1951 to 1954, coins were made of steel which was plated twice, first with nickel and then chromium. The plating was applied before the blanks were struck, so the edges of these coins are dull or even rusted. The composition was returned to pure nickel after both wars. More recently, in 1982, the same copper-nickel alloy used in the American coin was adopted in the Canadian coin, with the ironic result that the nickel then contained less nickel than any other circulating Canadian coin except the cent. Since late in 2000, the nickel is now generally made with plated steel. Since the plating is now done after the blanks are punched, the edges of the modern coins receive the plating. Portions of the 2001 and 2006 issues were struck in cupro-nickel, and can be identified by the lack of the letter "P" under Queen Elizabeth's portrait, and for their non-magnetic quality.Starting with the 1942 tombac coins, the nickel was made dodecagonal, presumably to help distinguish it from the cent after it tarnished in circulation. Tombac was removed from the nickel in 1944 (to be replaced by steel, as noted during the Korean war) but the coins in Tombac, steel, or 99.9% nickel all remained twelve-sided until 1963.All of these coins were lighter than the U.S. version, which is minted to be as close as possible to five grams. Canadian 99.9% nickel five-cent coins are nearly half a gram lighter than this, and its present steel coins are a full gram lighter than U.S. "nickels."

==History==
The first ever Canadian five-cent coins were struck by the Royal Mint in London as part of the introductory 1858 coinage of the Province of Canada. The coins were the same size and general composition as the corresponding American coins of the time, so the five-cent coin was based on the half dime. Although the American denomination was introduced as a larger copper-nickel coin in 1866, and the five-cent silver was retired in 1873, the Canadian five-cent coins remained small and silver until 1922.
All Canadian coins (including five-cent coins) were struck in England at the Royal Mint (no mint mark) and the Birmingham Mint (H mint mark) until 1908, when the Ottawa branch of the Royal Mint opened. With the exception of some 1968 dimes struck at the Philadelphia Mint, all Canadian coins since 1908 have been minted in Canada.
