The “Big Four” are the 4 animals everyone visiting Alaska wants to see. The Caribou, Dall Sheep, Moose and Grizzly Bear. These medallions are available in golden bronze, 1 oz .999 fine silver, 1 oz single gold relief (24k plating on parts of the front of the silver coin) and 1 oz double gold relief (24k gold plating on both sides). The 1 oz medallion is similar in size to a silver dollar. They are packaged in an airtight container and handsome gift box. The reverse is our Land of the Midnight Sun design.
