I do just about everything that John mentioned. I even had Cindy make me tee shirts and a sweatshirt that says "I BUY CASINO CHIPS" to wear whenever I go to yard sales or flea markets (which is every week). The shirt seems really silly but you would be surprised at the number of people who respond to it and have sold me their chips. I even have had two guys GIVE me their chips. I also pass out casino chips business cards whenever I can. I bought one collection of 1000 silver strikes from a guy who had my card (from 5 years earlier) and his estate called me about them. I tell people that even if they don't want to sell today to put my card with the chips then whenever they do want to sell they can call me.
