I guess it's what the coin dealers figure will be a hot item during limited hours - that translates to silver U.S. coins and of course Things Golden. More tokens than chips turn up at the big Long Beach Coin Show these days, although I have found some interesting things there. Harder work, but estate sales, flea markets, and of course your antique store route are probably more reliable. You seem to have consistently good luck at turning up the old and unexpected!
