Token coins are objects that replace or stand in for regular money. They have varied characteristics and uses.
They are characterized by different denominations, sizes, colours and shapes. They can be made of leather, Bakelite, tin, brass, aluminum, pewter and copper. They are issued by national or local governments to act as a free and exchangeable representation of regular money or goods. These can be used when inflation is so high and money supply is very low. In some countries they are used in the place of money to board subway trains and buses. They can also be issued legally by varied individuals, associations, groups or private companies.
