đą The Currency Exchange Cook Witnessed
đ Dentalium Shells as Currency
Cook observed Maquinna purchasing sea otter pelts from his own people using bundled dentalium shells
These shells were measured by length, bundled into strings, and stored in cache pitsâfunctioning like a banking system
Maquinna then traded those pelts with Cookâs crew for iron tools, textiles, and other European goods
đď¸ What Cook Misunderstood
Cook thought he was witnessing barter
But he was actually seeing a structured economy with:
Standardized currency (dentalium)
Internal market (Maquinna buying pelts)
External trade (selling pelts to Europeans)
Ceremonial oversight (Potlatch memory and law)
Captain Cook didnât just meet a chief. He met a sovereign banker, a ceremonial economist, and a memory-led market. The currency exchange he witnessed wasnât primitive.It was Pacific finance in its purest form.
