500 Francs Orangutan

Cameroon's wildlife-themed bullion issues are produced under licensing arrangements that route through the Banque des États de l'Afrique Centrale, though the coins themselves are struck by European private mints — in this case almost certainly Bild Münzguss or a comparable German contractor. The legal tender face value is nominal; no 500-franc silver coin circulates in Cameroon or anywhere in the CFA franc zone.

The Bornean and Sumatran orangutan was listed as Critically Endangered by the IUCN in 2016, a reclassification that drove a wave of collector issues across multiple issuing authorities simultaneously.
