Dinka Copper Currency, Sudan, Based

A heavy ring, copper and wood, meant to settle debts rather than adorn ankles.

Dinka people of Sudan, East Africa, made this currency ring in copper and wood in the early 20th century. Heavy metal rings were commonly used in parts of Africa as stores of value, including for bridewealth and exchange. This piece is a thick open circle, deeply colored, with small squared patches set into its face at intervals. The surface is rich brown with an aged, worn texture, and it stands on a slim black metal mount.

About eleven inches across. A coin you would need a wall to spend.
