500 Francs CFA Blue peacock

Cameroon's commemorative program has leaned heavily on exotic wildlife themes over the past decade, largely driven by the European novelty coin market rather than any domestic collecting tradition. Rhodium plating over silver — used here in place of standard proof finishing — became fashionable among Pacific and African issuing authorities around 2015 as a way to differentiate product in an increasingly crowded commemorative space. The blue peacock itself is native to the Indian subcontinent, not Central Africa, making this a wildlife issue with no particular connection to Cameroon's fauna.
