10 000 Francs CFA Sea Turtle

Benin issues coins through the BCEAO monetary framework shared across eight West African states, which means its numismatic program operates largely as a licensing arrangement with European minting houses rather than any domestic production capability. The 10,000 CFA franc face value is nominal fiction — convertible at a fixed rate to the euro through the French Treasury guarantee that has underpinned the CFA franc since 1945, the coin's stated value bears no relationship to its silver content or its collector market.

The one-kilogram format places this squarely in the modern bullion-meets-collector segment that proliferated after 2010, with Benin among several BCEAO member states that began licensing their sovereign name for high-relief silver issues aimed entirely at European and Asian collector markets.
