Canadian nickels were "coin silver" (800 parts silver) or sterling silver (925 parts silver) until 1922. These coins were discontinued in 1921. Many coins have been melted due to their high silver content. They're scarce now.
Another great collector's coin is the 1936 "dot" dime, which sold for $184,000. The 1936 design was modified to include the dot in this 1937 dime. These coins are rare—maybe five. They're worth $144,500–$245,000 CAD.
This "king of Canadian coins," the 50-cent piece, is rare and may only be 50-100 in circulation. Many of these coins were struck in 1921, but few circulated. Most of them were melted down to make later 50-cent pieces.
The late 19th century produced several Queen Victoria 50-cent pieces, although few remained in mint or near-mint condition. These perfect examples go for a lot at auction. CAD values for 1899 Victoria 50-cent coins range from $103 to $50,150.
World's most valuable coin was the 1911 Canadian silver dollar. Canadian silver dollars were only made twice; one is in Ottawa's Canadian Currency Museum. Only one 1911 Canadian silver dollar is available to collectors.
British one-pound gold sovereigns were struck at the Royal Canadian Mint from 1908 to 1919. About 50 1916 C gold sovereigns exist. Uncirculated 1916 gold sovereigns cost $33,300–$218,000 CAD.
An miscalculation caused the 10-cent 1969 coins to be struck with a large date instead of a tiny date. The 1969 large date 10-cent coin is rare—only 20–30 exist. They're worth $11,300–$21,900 CAD.
The Royal Canadian Mint planned a nickel 5 cent coin for 1922 in 1921. The mint melted down all its silver 5 cent pieces, mostly 1921s, before its debut. Only 400 silver 5-cent coins appear to have survived. The auction price for these coins is $2,261 to $67,082 CAD.
