Some history:
[FONT="]Charge coins are believed to have been first issued around 1865. At first they were made of celluloid, which is an early form of plastic. Later ones were made of copper, aluminum, steel or white metal, which is when they became known as charge coins. They came in various shapes, in sizes from a quarter to half-dollar. Not all were round; some were triangular and others had unique shapes. These credit pieces were mainly issued by department stores, and usually displayed the customer's identification number and an image connected with the merchant.
