1000 Francs CFA

The BCEAO's 1000 Francs series running from 2003 onward is notable primarily for the administrative record embedded in its signature combinations. Across roughly two decades of issuance, the note carries thirteen documented signature pairings — an unusually high turnover that reflects the rotating ministerial appointments across eight member states rather than any institutional instability at the central bank itself. The BCEAO presidency and the national minister countersignatures shift independently, which is why the same individual can appear across multiple years in different pairings.

The 2011 pairing is the most collectible: José Mário Vaz, who signed as Guinea-Bissau's finance minister, later became president of that country in 2014. Signed notes by heads of state are always a minor specialty within West African paper.
