2000 Francs CFA Mech Butterfly

The Bank of Central African States issues currency on behalf of six member nations — Cameroon, Central African Republic, Chad, Congo, Equatorial Guinea, and Gabon — all bound to a fixed parity with the euro through a French Treasury guarantee that dates to the post-colonial monetary agreements of 1972. The CFA franc itself is older, established in 1945 when France pegged its colonial territories to the new postwar monetary order.

The mechanical butterfly format belongs to a genre of high-end numismatic novelty issues that BEAC has increasingly licensed to European minting operators targeting the collector market rather than circulation. The 62.2g two-troy-ounce specification confirms this is a bullion-adjacent collectible with no plausible circulation intent.
