20 Dollars - Elizabeth II Georgian Bay National Park

Georgian Bay National Park was established in 1929 to protect the thousands of islands along the eastern shore of Georgian Bay — the so-called "30,000 Islands" coastline, the largest freshwater archipelago in the world. This coin belongs to the Royal Canadian Mint's fine silver National Parks series, which ran through the mid-2000s and drew consistent collector interest largely because mintages were capped low enough to sell out without secondary market speculation driving prices aggressively upward.

The .9999 fineness, rather than the more common .999, was a deliberate marketing distinction the Mint adopted during this period to differentiate its collector bullion output from competitors.
