Commodity value is of particular significance in the study of currency. For example, the commodity value of a coin is the value of the metal of which it is made. Gold and silver coins have a high commodity value, whereas fiat coins such as modern day quarters have a low commodity value. This is of particular historical relevance when analyzed in light of Gresham's Law.
Surplus Value. Value created by the unpaid labor of wage workers, over and above the value of their labor power, and appropriated without compensation by the capitalist. Surplus value is a specific expression of the capitalist form of exploitation, in which the surplus product takes the form of surplus value. The production and appropriation of surplus value constitute the essence of the fundamental economic law of capitalism.
