500 Francs California gold rush

The BEAC issues commemoratives with some regularity, but this piece — tying a Central African monetary authority to the California Gold Rush of 1848–1855 — has no meaningful historical connection between issuer and subject. It belongs to the broad category of legal-tender novelty issues produced for the collector market rather than circulation, a practice the BEAC and similar authorities have leaned into since the 2000s as a secondary revenue stream. The aluminium-brass composition makes the economics plain.
