Slave beads were basically worthless glass beads used between the 16th and 20th Century as a currency to exchange for goods, services and slaves (hence the name). Made to ease the passage of European explorers and then traders mainly across the African continents the beads were made throughout Europe, although the Venetians dominated production. Literally tons of these beads were used for this purpose.

The success of this form of currency can largely be attributed to the high intrinsic value African people put upon decorative items. Social status could be easily determined by the quality, quantity and style of jewellery worn. This cultural trait made the trade very easy to set up.

The beads were not of a set design, but as today, were produced according to demand. As the trade progressed throughout Africa, the influence of the region could be seen as tribal designs appeared in beads, and ancient traditions were revived with African Kiffa and Bodom beads being among those produced. These beads remain highly collectable today.
