Token coin

In the study of numismatics, tokens are coin-like objects used instead of coins. The field of tokens is part of exonumia. Tokens are used in place of coins and 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.

Currency tokens

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.
