100 Francs CFA Woolly mammoth

The Republic of the Congo issued a series of prehistoric animal coins in the early 1990s aimed squarely at the collector market — these never circulated domestically and were sold through numismatic distributors. The mammoth piece was part of a broader African issuer trend during this period, where nations with minimal numismatic infrastructure licensed their coinage rights to foreign minting and marketing firms, primarily European, who handled design, production, and distribution entirely.

Brass strikes of this weight tend to show uneven coloration over time due to alloy oxidation, a known characteristic of the type rather than a grading concern.
