50 Centimes - Albert I French text

Belgian Congo's subsidiary coinage of the 1920s was administered under the Comité Spécial du Katanga framework, with currency policy dictated from Brussels rather than Leopoldville. The French-text issues were struck for distribution in predominantly Francophone administrative districts, with parallel Flemish-text versions — KM#23 — issued simultaneously to satisfy Belgium's domestic linguistic politics, a compromise that extended even into colonial monetary administration.

Copper-nickel was chosen specifically to resist tropical humidity, after earlier bronze issues corroded badly in equatorial conditions.
