100 Francs CFA Polacanthus

The Republic of the Congo issued a run of copper-nickel dinosaur coins in the early 1990s, targeting the international collector market rather than domestic circulation. These pieces were produced under licensing arrangements common among smaller francophone African states during this period, with the actual minting carried out by European facilities entirely disconnected from Brazzaville. The Polacanthus — an ankylosaur-family genus known primarily from Early Cretaceous deposits in England — had no particular connection to Central Africa, chosen purely for collector appeal.

KM#16 is part of a multi-type series from the same year.
