Katanga cross, Luba people, DR Congo Copper Height with stand 31 cm A Katanga Cross (French: croisette du Katanga), also called a handa, is a cast copper ingot in the shape of an equal-armed cross which was once used as a form of currency in parts of what is now the Democratic Republic of the Congo (DRC) in the 19th and early 20th centuries. Katanga crosses were made in various sizes, typically about 20 centimetres (7.9 in) across, and weighing about 1 kilogram (2.2 lb). The name derives from Katanga, a rich copper mining region in the south-eastern portion of the DRC. These X-shaped ingots were cast by local coppersmiths by pouring molten copper into sand molds. To give an indication of their commercial value: 3 pieces would buy a goat; 3-5 pieces would buy a male slave and 5-10 a female slave. This cross has a remarkable coral red color. It is mounted on a metal stand.
