Mbole currency, often referred to as 'the perfect form,' was worn around the ankle as a display of status by both women and men of the Mbole tribe. Formed from copper, mboles were exchanged during marriage ceremonies. Copper was worked in Africa five-hundred years before the use of iron. This ancient material is associated with water and fertility. These are the ideal pieces for everyone. Whether you are focused entirely on design, or are building a serious collection of currency, you'll fall in love with these beautiful pieces. The age and patina varies with each one, as does the height of the custom-built stand.
