Wow! Thanks for all the responses. I've had some offers all over the board and a wide range of suggestions as to how much they are worth as well as the best places to sell them. For those of you asking "how much?" I was basically getting on this site for someone to tell me. Unfortunately, I don't think I'm any closer to an answer as I got suggestions all over the board (everything from 50 cents each chip to $40 apiece). I think I'm going to have to hang on to them for now and do some more research on my own. Thanks!
