20 Francs Megalodon

The Democratic Republic of the Congo has operated an aggressive commemorative bullion program since the early 2000s, licensing its sovereign issuing authority to European minting houses — primarily the Bavarian State Mint and B.H. Mayer's — to produce collector coins that have no meaningful circulation in Kinshasa. The "Megalodon" issue is part of a prehistoric shark series aimed squarely at the international thematic collector market.

Otodus megalodon went extinct roughly 3.6 million years ago. No confirmed complete skeleton has ever been recovered — the cartilaginous skeleton rarely fossilizes — leaving tooth morphology as the primary basis for size estimates.
