This silver dollar, struck by the Royal Canadian Mint in 1989, commemorates the 200th anniversary of Sir Alexander Mackenzie's historic 1789 expedition to the Mackenzie River, a pivotal moment in the exploration of Canada's Northwest. The obverse features a detailed profile of Queen Elizabeth II, framed by the inscription "ELIZABETH II D.G. REGINA," anchoring the coin to Canada's constitutional monarchy. The reverse depicts Mackenzie and his companions navigating the turbulent Mackenzie River in a canoe, set against a backdrop of rugged cliffs and boreal forest, with the inscription "FLEUVE MACKENZIE RIVER" and "DOLLAR" below. Struck in 500 fine silver, this coin captures the spirit of adventure and discovery that shaped Canada's national identity. Do You Know? Sir Alexander Mackenzie's 1789 expedition was the first recorded journey to the mouth of the Mackenzie River, a major waterway that stretches over 4,000 kilometers from the Northwest Territories to the Arctic Ocean. The expedition, commissioned by the North West Company, aimed to find a Northwest Passage to the Pacific, and while Mackenzie did not achieve this goal, his journey significantly expanded European knowledge of Canada's interior. The 1989 silver dollar, designed by Ontario artist John Mardon, was part of a series of commemorative coins celebrating Canada's exploration heritage, and its detailed reverse design captures the harsh beauty of the Canadian North.
