Token coins

In the study of numismatics, token coins or trade tokens are coin-like objects used instead of coins. The field of tokens is part of exonumia and token coins are token money. Tokens either have a denomination shown or implied by size, color or shape. "Tokens" are often made of cheaper metals: copper, pewter, aluminium, brass and tin were commonly used, while bakelite, leather, porcelain, and other less durable materials are also known.

The key point of difference between a token and a coin is that a coin is issued by a governmental local or national authority and is freely exchangeable for goods or other coins, whereas a token has a much more limited use and is often (but not always) issued by a private company, group, association or individual. In the case of "currency tokens" issued by a company but also recognized by the state there is a convergence between tokens and currency.

In their purest form, currency tokens issued by a company crossed the boundary of merely being "trade" tokens when they were sanctioned by the local government authority. This was sometimes a measure resulting from a severe shortage of money or the government's inability to issue its own coinage. In effect, the organization behind the tokens became the regional bank.

A classic example of this is the Strachan and Co trade tokens of East Griqualand in South Africa which were used as currency by the indigenous people in the region from 1874. Their initial success resulted from the scarcity of small change in this remote region from that time.

Similarly, in times of high inflation, tokens have sometimes taken on a currency role. An example of this is Italian or Israeli telephone tokens, which were always good for the same service (i.e., one phone call) even as prices increased. New York City Subway tokens were also accepted sometimes in trade, or even in parking meters, since they had a set value.
