Nsirewa

Nsirewa, cowrie shells, references the shells that served as currency and as a store of value across large parts of West Africa before and alongside colonial-era coinage, and Willis records the symbol standing directly for wealth, economic prosperity, and the accumulated value that trade and careful management can build, a meaning that follows from the shells' real, documented historical function as circulating money rather than from any purely decorative or ornamental association the shells might also have carried. He notes cowrie shells' actual monetary use extended across a wide trading network reaching well beyond the Akan region specifically, so Nsirewa's proverb draws on a shared regional economic history broader than the Adinkra corpus's more locally specific symbols such as Nsaa's northern Ghanaian textile trade.

Willis notes cowrie shells are typically rendered in this design as a cluster of small oval forms rather than as a single large shell, a compositional choice emphasizing accumulated quantity, wealth built up through gathering, over any single shell's individual value, consistent with how the shells actually functioned as a counted, accumulated currency rather than as individually prized objects.

Willis records Nsirewa's meaning sitting alongside Bese Saka as one of the Adinkra corpus's most direct symbols of material abundance, and distinguishes the two by register: Bese Saka draws on kola nuts, a traded commodity consumed and exchanged in ordinary commerce and hospitality, while Nsirewa draws on cowrie shells specifically as currency, the abstract store of value itself rather than a good exchanged for it. He notes this makes Nsirewa read somewhat more directly as a symbol of accumulated wealth in the pure financial sense, comparable in that specific focus to how a modern currency symbol might function, distinct from Bese Saka's more communal, hospitality-inflected reading of abundance.

Willis treats Nsirewa's currency-specific focus as giving it a documented historical precision the corpus's more general prosperity symbols lack, noting that cowrie shells' actual exchange rates and circulation are independently attested in West African economic history well beyond the Adinkra tradition's own use of the shells as a proverbial image. Willis treats this documented economic precision as unusual strength for a symbol whose underlying commodity, unlike kola nuts or land, no longer circulates as living currency today.
