12 Dollars AK-47 rifle

Liberia has a long history of issuing novelty bullion and commemorative pieces targeted squarely at the collector market rather than circulation, and this falls firmly in that tradition. The AK-47 designation references the Kalashnikov rifle adopted by Soviet forces in 1949 — an odd subject for a West African nation whose official currency is the Liberian dollar, and whose government has no particular historical tie to the weapon beyond its ubiquity across the continent.

At 0.031 g, this contains fractionally less gold than a 1/1000 oz piece.
