1000 Tögrög Bison

Mongolia has maintained wild bison populations in the Khustain Nuruu reserve since reintroduction programs began in the 1990s, and the country has increasingly issued large-format silver bullion pieces tied to its native megafauna as a deliberate revenue strategy for the Mongol Bank. The 62.2g format — a troy ounce double — positions this squarely in the premium bullion segment rather than the collector proof market, despite the .9999 fineness being finer than most sovereign bullion standards.
