10 000 Francs

The Banque des États de l'Afrique Centrale served six Central African nations under a shared franc zone, meaning this note circulated as legal tender across a currency union — the issuing authority was supranational, but the overprint and signature combination here anchors it specifically to the République Populaire du Congo, Brazzaville's Marxist-Leninist state at the time. Oye Mba served as BEAC Governor into the mid-1980s; the pairing with Tchepannou as the Congolese national signatory is specific to this short issue window.

Banque de France intaglio production at this denomination level was standard for the zone, but the 10 000 franc value was the highest circulating note in the BEAC series at the time — serious purchasing power in an economy where official salaries were often paid months in arrears.
