3000 Francs New York, black rhodium

Cameroon has issued commemorative silver under its own authority since the 1970s, but the volume of modern collector issues bearing its name has accelerated sharply since the 2010s — most produced by European minting houses with no physical connection to Yaoundé. This piece is part of that wave: a 100g black rhodium-plated silver issue in the "city series" format that several mints have sold aggressively to the novelty collector market.

Black rhodium plating on silver blanks is an electrochemical process prone to micro-adhesion failures over time, particularly at high-relief edges. Worth monitoring on stored examples.
