Types and Functions of Money


Commodity Money

Cattle and small domestic animals, shells, pearls, whale teeth, feathers, implements, jewelry, stones, salt, grain, dried fish, cocoa beans, tea, sugar, cotton cloth, furs, tobacco, metal, paper … the range of goods that have been used as money is virtually boundless. Depending on the time and location, money substitutes have been used time and again even in highly developed monetary economies. Immediately after World War II, for example, cigarettes, coffee and other prized goods were accepted legal tender. 

What material money is made of appears to have no bearing on its function. Only in the case of commodity money has the exchange value been directly linked to the material used. Whether the first coins made of electrum in Asia Minor in the 7th century B.C. were commodity money or not has not been answered conclusively to this day. The weights of the coins were standardized, and the coins were struck with dies to create images, usually figurative representations of animals. However, it is not clear whether the coins were actually traded according to value or whether the coins were simply used according to weight, like metal bars. John Maynard Keynes held that these coins were stamped simply out of daring vanity, national pride or for advertisement purposes, so that minting had no greater importance and at best certified metal quality.

Coins, Paper Money and Electronic Money

Coins that were accepted for their nominal value represented a sea change in monetary history. Experience has shown that the value of coins vouched for by the inscription of the ruler’s name was not always identical with the actual value of the coin, which was the result of its weight and metal fineness. Marc Shell, literary analyst, identified a difference between “intellectual currency” and “material currency.” In the case of paper currency, the difference between the material and monetary value became even more striking and the link between the nominal value of banknotes and the substance of money became even more tenuous. Finally, the link to substance has been abandoned completely in the case of electronic money – only the symbol remains.

No matter what form money takes, its defining elements are that it is (1) a medium of exchange, and as such is (2) a measure of the value of assets, i.e. a unit of account, and it can be used as a (3) a store of value. Any asset can be used as money, provided it is accepted as such by the power of convention or general agreement and positive experience and provided that people have trust in its value and its stability.
