10 Francs Butterfly Fish

The Democratic Republic of Congo has issued commemorative silver coinage under the Banque Centrale du Congo since the early 2000s, largely targeting the collector market rather than domestic circulation — a fiscal strategy common among smaller economies seeking hard currency from foreign numismatic buyers. These pieces were never intended to pass through Congolese hands.

KM#179a is the silver variant of this issue; a base metal version also exists under the same series.
