5000 Francs

The Banque des États de l'Afrique Centrale issues a single currency — the CFA franc — across six member states of the CEMAC zone: Cameroon, Central African Republic, Chad, Republic of Congo, Equatorial Guinea, and Gabon. Each country receives notes with a letter code identifying the issuing national agency, which makes signature combinations a reliable tool for attribution. The three signature variants cataloged here reflect governor-level changes at the BEAC central directorate between roughly 2002 and the mid-2000s, with Aleka-Rybert holding the cashier position across all three.

509Fc, bearing the Abaga-Nchama signature, is the scarcest of the three in circulated grades.
