100 Francs CFA Essai

The Banque Centrale des États de l'Afrique Équatoriale et du Cameroun was itself a transitional institution — established to serve the post-independence francophone states of Central Africa but already being restructured into the Banque des États de l'Afrique Centrale by 1972. This essai was produced as a struck trial piece for circulation coinage approval, a standard step in the French monetary system administered through the Paris Mint. Whether this design advanced to circulation or was superseded is answered by the KM numbering alone — it did not.
