300 Ngultrum Snow Leopard

Bhutan's snow leopard conservation coinage of the early 1990s was issued in conjunction with the WWF's global wildlife series, which commissioned national mints and monetary authorities across dozens of countries to produce silver pieces tied to endangered species programs. The Royal Monetary Authority used these issues partly as a hard currency revenue mechanism — Bhutan's domestic economy had little use for a 300-ngultrum silver coin.

The snow leopard population in the Bhutanese Himalayas was estimated at fewer than 200 animals at the time of issue.
