Chamba Iron Currency, Nigeria, Based

A ring open at the top, with two horns that wind like tendrils.

Chamba people of Nigeria, West Africa, forged this iron currency in the 20th century. Iron bands and rings of this kind circulated as trade money and bridewealth across parts of West and Central Africa, valued by weight and by workmanship. A smooth, thick hoop opens at the top into two slender, twisting prongs that curve outward. The iron has weathered to a warm rust-orange with a dry, pitted skin. It stands on a slim black metal mount.

About 18 inches tall on its stand. Money that never needed a wallet, only a wall.
