Canadian Silver Maple Leaf bullion coins are one of the world's most recognised silver bullion coins. After the success of the Canadian Gold Maple Leaf coin, the Royal Canadian Mint began producing the Silver Maple Leaf in 1988. The silver bullion coin is the 'official legal tender', and its content, weight and purity are guaranteed by the Canadian government. The Canadian Silver Maple Leaf bullion coin has the lowest mintage of any silver coin in North America, resulting in its high demand. The silver bullion coin has a face value of $5 Canadian, the highest face value of any comparable silver bullion coin. It is minted with one troy ounce of fine silver. Its 999.9 purity means that it is the purest silver coin in regular mintage. The Royal Canadian Mint is recognised by the London Bullion Market Association as an acceptable Good Delivery Refiner. They are traded as investment grade silver bullion in international precious metal markets.
