100 Francs Stegosaurus

The Democratic Republic of Congo has issued a long-running series of small-format gold coins under the Banque Centrale du Congo, with prehistoric fauna a recurring subject. The Stegosaurus piece fits squarely into that commercial bullion-and-collector program, produced almost certainly by a European private mint under licensing arrangement — a common model for sub-Saharan nations with limited domestic minting infrastructure.

At 0.5 grams of .9999 gold, these are essentially novelty fractionals with negligible bullion value. The market for them is driven entirely by the collector series, not metal content.
