Be carefull about excluding "chip" as many sellers do dice and chips and mention that in thier auctions. here is my search:

casino dice -(bunco, bracelet, pin, system, lighter, coupon, aluminum, dvd, cd, vhs, movie, software, program, fabric, shirt, tie, mice, poker, rockabilly, jewelry, comics, secrets, beads, necktie, buckle, battletech)

it cuts out most of the garbage
