100 Francs CFA

The BCEAO franc zone is a direct continuation of the colonial CFA franc system established by France in 1945, and the eight member states that use this currency — including Senegal, Mali, and Côte d'Ivoire — have no independent monetary policy. The franc is pegged to the euro at a fixed rate of 655.957, a parity inherited from the old franc at conversion and guaranteed by the French Treasury, which holds a portion of member states' foreign reserves in Paris.

The nickel-plated steel composition adopted for this type replaced an earlier nickel alloy, reflecting the broader African shift toward cheaper substrate metals as raw nickel prices spiked in the mid-2000s.
