The Word, Currency, is in common Use in the Plantations . . . and signifies Silver passing current either by Weight or Tale. The same Name is also applicable as well to Tobacco in Virginia, Sugars in the West Indies &c. Every thing at the Market-Rate may be called a Currency; more especially that most general Commodity, for which Contracts are usually made. And according to that Rule, Paper-Currency must signify certain Pieces of Paper, passing current in the Market as Money. (emphasis in original)
