500 Francs

The BEAC's 500 Franc notes of this period carried a single constant signature — Mamalepot held the senior position throughout the entire run while the countersignatory changed six times across eight dated issues. That pattern reflects genuine institutional turbulence within the bank's governance structure during the 1990s, not routine rotation.

P#201E circulated across six member states of the CEMAC zone simultaneously, each accepting the same physical note regardless of which country's central bank branch had issued it — a monetary arrangement with few direct parallels in postcolonial Africa.
