Credit card
Design and vintage credit cards as collectibles

The design of the credit card itself has become a major selling point in recent years. A growing field of numismatics (study of money), or more specifically exonumia (study of money-like objects), credit card collectors seek to collect various embodiments of credit from the now familiar plastic cards to older paper merchant cards, and even metal tokens that were accepted as merchant credit cards. Early credit cards were made of celluloid plastic, then metal and fiber, then paper, and are now mostly polyvinyl chloride (PVC) plastic. However, the chip part of credit cards is made from metals.
