definition v2 of coinage

Coinage is a kind of money: the stock of minted coins circulating in a monetary system, struck by a mint under an issuing authority and accepted as a medium of exchange. PARAMETERS: (1) standard — the metal or token substrate and the weight-and-assay standard the coins are struck to; (2) denomination — the unit of account each coin's stamp represents; (3) issue — the authority (mint, state, or issuer) whose stamp guarantees the coin's acceptance. PERSISTENCE: monetary convention — the issuer's guarantee, acceptance in trade, and the continuity of the mint's issue keep the stock circulating; individual coins wear out and are withdrawn, but the coinage endures while the convention of acceptance holds.
