50 Francs

The BEAC issues coinage on behalf of six member states — Cameroon, Central African Republic, Chad, Gabon, Equatorial Guinea, and the Republic of the Congo — all sharing the CFA franc under a monetary agreement with France that fixes the currency to the euro at a guaranteed rate. The arrangement dates to 1972 for the BEAC specifically, successor to earlier colonial-era institutions. France holds a seat on the BEAC board and requires a portion of member foreign exchange reserves be deposited with the French Treasury.

Nickel clad steel replaced earlier nickel compositions across the BEAC series as raw material costs rose — a quiet technical shift that most circulation users never noticed.
