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.
