The 1/2 oz Canadian Gold Maple Leaf coin is one of the purest gold coins in the world, with most Maple Leaf coins being minted with .9999 fine 24-Karat gold. Although their high purity does not make them highly conducive to heavy circulation, the Canadian Maple Leaf is loved around the world, and is especially well-recognized in North America.
Minted by the Royal Canadian Mint, the Maple Leaf coins date back to 1979. At the time of their release, the only other popular gold bullion coin in production was the South African Krugerrand. This makes the Canadian Maple Leaf one of the oldest of the modern gold bullion coins. The face value of the 1 Oz Gold Maple Leaf varies based on year. The most recent 1/2 oz Gold Maple Leaf coins have a $20 face value. Maple Leaf coins minted from 1979-1982 have .999 purity, while all coins after November 1982 have at least .9999 purity.
