UGANDA. MANILLA BRIDGE SHAPE 1850/1900. BRONZE 1344 gr. (47,04 oz) - 25,5x17x3 cm (9,9x6,6x1,2 inch). Manillas are penannular armlets, mostly in bronze or copper, very rarely gold, which served as a form of commodity money (and, to a degree, ornamentation) among certain West African peoples (Aro Confederacy, Guinea Coast, Gold Coast, Calabar and other parts of Nigeria, etc.). This form of African currency also became known as "slave trade money" after the Europeans started using them to acquire slaves for the slave trade into the Americas (as well as England prior to 1807).
