Abstrakt: The West African currency manillas produced by Europeans should be strictly distinguished from African bracelets and anklets and be classified according to their origin. shape and metal composition. Portuguese tacoais manillas were the first such currency exported from Europe to West Africa. Later there were so - called Birmingham manillas from England, alongside French or English POPO manillas. Little is known about the origins of Portuguese tacoajs manillas other than that they were produced in Flanders and Gennany, delivered to Portugual via Antwerp and then traded in West Africa. In the present stildy, tacoais manillas found in a Portuguese shipwreck by the Cape Verde Islands were examined using elemental and isotope analyses for metal provenancing. We were able to demonstrate that the metal composition of Birmingham manillas and tacoais manillas are clearly distinct. The chemical composition and lead isotope abundance ratios of facoais manillas from Cape Verde Islands dated to 1586 and a rectangular copper plate ingot from the Elbe ship week near Wittenberge of around 1622 indicate that both artifacts had their origins in the copper deposits of Banskh Bystrica (formerly Neusohl) iii Slovakia and in part in the lead (lead/zinc) deposits in the Aachen-Stolberg districts of Germany.
