1000 Francs CFA

The CFA franc zone is one of the few currency unions in the world where the finance ministers of member states co-sign the banknotes alongside the central bank governor — which is why this series carries two signatures, not one, and why those signatures change so frequently. Each pairing reflects a different national finance minister rotating into the signing authority alongside the BCEAO governor, meaning the same note design can carry over a dozen distinct signature combinations across a single print run span.

José Mário Vaz, whose name appears on the 2010 date, later became President of Guinea-Bissau in 2014 — a rare instance of a banknote signatory reaching a head of state position.
