West African Gold Dust Trade

Timeline

1. c. 1400–1480Volta Basin goldfields · GhanaAkan polities gathered gold grains from alluvial river deposits, purified them by blow-pipe and panning, tested fineness with a blow-pipe, and packaged them into weighable units for inland and coastal trade, forming a metallic currency culture independent of coinage.
2. 1480–1610Elmina (St. George's Castle) · Gold CoastAfter Portugal built its fortress at Elmina in 1482, European traders exchanged metal goods, cloth, and salt for packaged gold powder; from the sixteenth century Dutch and other competitors joined, and gold dust became a key medium of exchange linking Akan inland mining, trans-Saharan caravans, and European Atlantic trade.
3. 1611–1620Gold Coast (Komenda–Elmina) · Gold CoastIn the 1610s, English, Dutch, and Portuguese merchants competed to acquire gold dust on the Gold Coast; the Dutch West India Company gradually expanded its posts, and Akan middlemen exchanged gold powder for copper goods, firearms, and textiles. Gold dust exports in this period supplied part of Europe's and North Africa's monetary metal, while intensifying coastal-inland political rivalries.
4. 1700–1900Kumasi · GhanaAfter the Ashanti Empire unified the Akan goldfields in the eighteenth century, gold dust trade continued to flow to Europe via coastal forts until British colonial rule in the nineteenth century introduced the pound and a customs system, gradually causing traditional gold powder trade by weight to decline.
