Casino gaming tokens are part of the area of numismatics known as exonumia. Although the metal tokens that were used for decades in slot machines are no longer used in a technologically advanced gaming industry that calculates everything electronically, old casino gaming tokens have become highly collectible. The chips that are used for card games, dice games and roulette are also referred to as casino gaming tokens and are also very desired by collectors, especially when they were issued by some of the legendary casinos of the old west. Try your luck at finding one of these neat pieces of history at Black Mountain Coins.
