You can buy a set of 100 "Bee" chips that are just plastic. 50 white, 25 red, and 25 blue. The gang I play cards with has about 3 or 4 sets of these spread out amongst us. Generally they are used at the cottage and with the kids. They are worth what they cost, which is to say about a nickel apiece.
Most folks will say "Dice" chips, but they too serve a purpose. I owned two sets of 500 before getting into the higer end of the market.
