In the field of economics, the commodity value of a good is its free market intrinsic value under optimal use conditions. In a free market, the commodity value of a good will be reflected by its price. For example, if an acre of land can yield a net of 100 dollars loss by lying fallow, 50 dollars gain by being planted with corn, and 100 dollars gain by being planted with wheat, then that acre's commodity value is 100 dollars; the farmer is assumed to put his land to best use.
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.
Asset backed debt has a commodity value equal to the price of the collateral; a loan backed by a house has a commodity value equal to the free market price of the house. Non-collateralized debt, on the other hand, does not have a commodity value; it is valuable only insofar as it is repaid.
