Exonumia
What is Exonumia?
Exonumia is the study of coin-like objects such as token coins and medals, and other items used in place of legal currency or for commemoration. This includes elongated coins, encased coins, souvenir medallions, tags, badges, counterstamped coins, wooden nickels and other similar items. It is related to numismatics proper (concerned with coins which have been legal tender), and many coin collectors are also exonumists. Items such as bus tokens (transportation tokens), bar or pub tokens, and casino tokens or chips are some of the more common forms of exonumia.
