English: A Katanga Cross, also called handa, is cast copper cross, of varying sizes but typically about 20 cm (8 inches) across, and weighing about 1 kilogram (2 pounds). They were used as a form of currency in parts of what is now the Democratic Republic of the Congo in the 19th and early 20th Centuries. Their name derives from Katanga, a rich copper mining region in the south-eastern portion of the country.
