2500 Tögrög Year of the Monkey

Part of Mongolia's long-running lunar series, this 2004 issue coincides with the Wood Monkey year in the sexagenary cycle. The Bank of Mongolia began producing large-format silver bullion commemoratives in the late 1990s as a hard-currency revenue stream — the tögrög itself being of limited convertibility — with these pieces sold almost entirely to foreign collectors and never intended for domestic circulation.

At 155.5 grams, the planchet is a standard 5-troy-ounce format widely used by smaller sovereign mints for the collector market of that period.
