Fungibles

Fungibles are movable effects which perish by being used, and which are estimated by weight, number, and measure, such as corn, wine, money. Things are fungible when their place can be adequately supplied by other individuals of the same class, as where a sum of money is repaid by means of other coins than those in which it was received. Thus, jewels, paintings, and works of art are not fungibles, because their value differs in each individual of the species without possessing any common standard.
