Commodity money Commodity money Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects that have value in themselves (intrinsic value) as well as value in their use as money. Examples of commodities that have been used as mediums of exchange include gold, silver, copper, salt, peppercorns, tea, large stones (such as Rai stones), decorated belts, shells, alcohol, cigarettes, cannabis, silk, candy, nails, cocoa beans, cowries and barley. These items were sometimes used in a metric of perceived value in conjunction to one another, in various commodity valuation or price system economies.
Commodity money as a theoretical backing for federally issued "gold certificates" to substitute for the gold. Between 1933 and 1970 (when the U.S. officially left the gold standard), one U.S. dollar was technically worth exactly 1/35 of a troy ounce (889 mg) of gold. However, actual trade in gold bullion as a precious metal within the United States was banned after 1933, with the explicit purpose of preventing the "hoarding" of private gold during an economic depression period in which maximal circulation of money was desired by influential economists. This was a fairly typical transition from commodity to representative to fiat money,
