nu·mis·mat·ics (n›”m¹z-m²t“¹ks, -m¹s-, ny›”-) n. (used with a sing. verb). Abbr. numis. The study or collection of money, coins, and often medals. --nu·mis“ma·tist (n›-m¹z“m…-t¹st, -m¹s“-, ny›-) n.
Money, Coins, and often Medals .... I would think would include chips, tokens, jetons, and other items used as or inplace of money.
I say chip collectors are NUMISMATISISTS, as well as a loose grip on a slippery slope!
