Canadian Silver Maple Leafs The Canadian Silver Maple Leaf is a silver bullion coin issued each year by the Royal Canadian Mint since 1988. The face value of the 1 oz coin is 5 Canadian dollars. The purity of the coin is .9999 silver, as opposed to .999 silver, the standard of most other major bullion issues. The coin always features a maple leaf and generally consists of 1 troy ounce (31.1 g) of silver. Annual variations for the coin in the past have included proof releases (1989 only), privy marks, a coloured maple leafs, holographic features and various designs, such as the 2010 Winter Olympics release. The one unifying feature in all silver maple leaf coins minted is the phrase "Fine Silver 1 oz Argent Pur" on the obverse of the coin.
