500 Francs CFA Papilio machaon

The Bank of Central African States — the BEAC — issues commemorative collector pieces well outside its ordinary monetary mandate, a practice that generates hard currency revenue from international numismatic markets rather than serving any domestic circulation function. The Papilio machaon, the Old World swallowtail, is not native to Central Africa; its range runs from Europe across temperate Asia, making its appearance on a BEAC issue a purely commercial choice aimed at European collector demographics.
