500 Francs

The Bank of Central African States — the BEAC — issues a single shared currency across six nations: Cameroon, Central African Republic, Chad, Republic of the Congo, Equatorial Guinea, and Gabon. The franc CFA itself is pegged to the euro at a fixed rate of 655.957, a relationship inherited from the colonial-era peg to the French franc established in 1948 and maintained through every monetary reform since.
