5 Francs Belgium - King Leopold I

This coin has nothing to do with Leopold I of Belgium, who died in 1865. The name is almost certainly a reference to the Congo Free State, the territory Leopold II held as personal property from 1885 to 1908 — one of the most brutally administered colonial regimes in recorded history. That the issuing authority is listed as the Banque Centrale du Congo places this as a late-20th-century Congolese issue invoking that history, likely for the collector market rather than circulation.
