I want to change this dollar bill into ten dimes

Sally exchanged a twenty-dollar bill for five-dollar bills

Instead of giving the money, that is the normal coin of the realm, which is the phrase that everyone used then, they would give them a token, and this token might be metal, might be wood, might be cardboard

With the token they could only go to the company shop and buy food or clothing from that shop

And the tokens he received as wages could only be spent at that shop

Almost all societies now have a money economy based on coins and paper bills of one kind or another

Money circulates through the banking system

In 1971 the United Kingdom changed its currency to the decimal system

It is without justification that money has been called one of the greatest inventions of man
