10 Dollars Rhino

Sierra Leone's late-1990s and early-2000s wildlife series was produced almost entirely for the collector export market — these coins never meaningfully circulated domestically, where the leone, not the dollar, remained the functional currency. The "dollar" denomination was a fiction calibrated for international sales channels.

The southern white rhinoceros was the subject of intensive conservation intervention during this period, with southern African populations recovering while the northern subspecies collapsed toward functional extinction. By 2001, fewer than 30 northern whites remained in the wild.
