In the late 1970s, the Royal Canadian Mint started producing Canadian Maple Leaf bullion coins, the first popular bullion coins produced from pure gold in the Americas. The obverse of the coin depicts Queen Elizabeth II, while a maple leaf theme graces the reverse side. Demand for this bullion coin has increased in recent years (particularly in the Northwest) due to its appealing design and stunning natural color. The Canadian Gold Maple Leaf comes in denominations of 1/10 ounce ($5), ¼ ounce ($10), ½ ounce ($25), and 1 ounce ($50).
