1000 Francs

The Institut d'Émission de l'Afrique Équatoriale Française et du Cameroun was a short-lived monetary authority, established in 1955 to manage currency for the four territories of French Equatorial Africa — Chad, Gabon, Middle Congo, and Ubangi-Shari — alongside Cameroun under a single unified framework. It was already an institution operating on borrowed time: decolonization was accelerating, and by 1960 each territory would be managing its own monetary arrangements through successor bodies.

Banque de France printing at this date guaranteed a high standard of intaglio work. The 1957 issue was among the final emissions under this authority before the political reorganization swept the framework away entirely.
