bullion

Etymology

From Middle English bulloin, bullioun, from Anglo-Norman bullion, of obscure origin, perhaps from French bouillon, extending the sense to that of ‘melting’. Middle Dutch boelioen (“base metal”) seems to have come from the unrelated French billon.

2. (obsolete) Base or uncurrent coin.
