100 Francs CFA Philippus

The "Philippus" name references the Roman antoninianus struck under Philip I (Philip the Arab), who reigned from 244–249 AD and is notable for having organized the Secular Games of 248 AD — Rome's millennial anniversary celebrations. This Congo-issued bullion piece belongs to a wave of small-denomination fractional gold coins that flooded the collector market from Central African franc-zone issuers after roughly 2015, where nominal face values bear no relationship to metal content and the issuing state's monetary authority is effectively ceremonial.
