25 Francs CFA FAO

The FAO designation ties this coin to a United Nations Food and Agriculture Organization campaign that ran from the late 1960s onward, pressuring developing-nation mints to dedicate circulating coinage to agricultural messaging. The BCEAO adopted the program early, and this denomination became the workhorse of that commitment across eight member states — Benin, Burkina Faso, Guinea-Bissau, Ivory Coast, Mali, Niger, Senegal, and Togo — all sharing identical coinage under a single monetary union that predates most of their political independence.

The franc zone arrangement itself traces to postcolonial agreements with France that guaranteed convertibility, a relationship that drew sustained criticism through the 1990s and accelerated calls for monetary reform still unresolved as of the coin's most recent strikes.
