500 Tögrög Bison

Mongolia's wild bison population was functionally extinct by the early 20th century, hunted out across the steppe long before modern conservation frameworks existed. This coin issues from Mongol Bank as part of a broader wildlife series drawing attention to species either lost from or critically reduced across the Mongolian plateau. The .999 fineness places it firmly in the bullion-adjacent commemorative category — priced for collectors, not circulators.
