Commodity money

Many early instances of money were objects which were useful for their intrinsic value as well as their monetary properties. This has been called commodity money; historical examples include iron nails (in Scotland), pigs, rare seashells, whale's teeth, and (often) cattle. In medieval Iraq, bread was used as an early form of currency.

The use of shells or ivory was nearly universal before humans discovered how to work with precious metals; in China, Africa, and many other areas, use of cowrie shells was common. In China the use of cowrie shells was superseded by metal representations of the shells, as well as representations of metal tools. These imitations may have been the precursors of coinage.

Salt and spices have been used as money. From 550 BC, accepting salt from a person was synonymous with receiving a salary, taking pay, or being in that person's service. Definite indications are available that both black and white pepper have been used as commodity money for hundreds of years before Christ, and several centuries thereafter. Being a valuable commodity, pepper has naturally been used as payment. Alaric I reportedly demanded 3,000 pounds in weight of pepper in 408 AD as part of a ransom for the city of Rome. In the Middle Ages, there was a French saying, 'As dear as pepper'. In England, rent could be paid in pounds of pepper, and so a symbolic minimal amount is known as a "peppercorn rent".

Even in the modern world, in the absence of other types of money, people have occasionally used commodities such as tobacco as money. This happened on a wide scale after World War II when cigarettes became used unofficially in Europe, in parallel with other currencies, for a short time. It also occurs in some remote parts of countries such as ColombiaBolivia, where cocaine, or its precursor, coca paste, is used as commodity money. and

Another example of "commodity money" is shell money in the Solomon Islands. Shells are painstakingly chipped into rough circles, filed down, and threaded onto large necklaces, which are then used during marriage proposals; for instance, a father may charge twenty shell money necklaces for his daughter's hand in marriage.
