10 000 Francs CFA Moby Dick

Benin has no particular connection to Melville's novel — the coin exists because the Central African CFA franc zone has become a reliable venue for third-party bullion and novelty issues aimed squarely at the collector market rather than domestic circulation. These pieces are produced under license arrangements that allow the issuing state to collect seigniorage fees while the actual commercial operation runs through European distributors.

The 1-kilogram format at .999 fineness places this firmly in the "investment novelty" category that expanded rapidly through the 2010s as silver spot prices stabilized and collector demand for oversized pieces grew.
