Stick-on inlays?, just like some of those...
crummy Bud Jones chips! Two of the chips shown have inlays that amount to nothing more than stickers. Shortly after Grand Casino Mille Lacs started to use "sticker inlay" Bud Jones chips, I was offered an "error" chip from a Blackjack dealer that worked at that casino. It was a $5/$25 chip, available to me for only $100. I declined to purchase that chip, and let my friendly dealer know that such "error" chips have no special value. Any quantity of these "error" chips can be created. It takes almost no skill and about 2 minutes to make one. All you need is a razor blade or a sharp knife to remove the inlay.
