5000 Francs CFA

The CFA franc zone is governed by two separate central banks — BCEAO covers the eight West African states, BEAC the six Central African ones — and the notes are not interchangeable despite sharing a name and peg to the euro. This 5000 franc denomination is the highest-value note in regular BCEAO circulation for most of the series' run, making the signature combinations more than bureaucratic detail: each pairing reflects a Minister of Finance and a BCEAO Governor, both of whom must countersign, drawn from different member states by institutional convention.

Nineteen distinct signature combinations across roughly sixteen years is an unusually dense rotation for a single Pick number, driven by the political volatility of member states — Guinea-Bissau's José Mário Vaz, for instance, later became that country's president before being ousted in a prolonged constitutional crisis.
