Origin
Cowerie shells (ensimbi ennganda) were first used as money during the reign of Kabaka Ssemakookiro Wassajja (1797 - 1814 ad), the 27th Kabaka in the Kintu Dynasty and eventually became legal tender in Buganda. Each shell was pierced so that a string could be passed through, the shells were then tied around the neck, or carried on the waist
