25 Francos CFA Essai

The Banque des États de l'Afrique Centrale — the common central bank for Cameroon, Central African Republic, Chad, Republic of the Congo, Equatorial Guinea, and Gabon — issued essais as trial strikes submitted for official approval before authorizing full production runs. KM#E29 belongs to that administrative process rather than to any circulation program, which is why surviving examples are confined almost entirely to the original presentation sets distributed to mint officials and issuing authority representatives.

Aluminium bronze was the standard alloy chosen for the circulating 25 Francs CFA across this period, making the essai compositionally identical to its production counterpart — the distinction lies entirely in its minting status and mintage figure, which for BEAC essais of this era typically numbered in the low hundreds.
