Quite a few of 'em....Gene! Frankly, I'm surprised that folks will bid so much for obsolete $500's but they won't purchase seven different $100 chips when they are available on the tables at face value for less money than what is being bid on a single $500 chip. I once asked one chipper, "how many current $100 chips from A.C. do you have in your collection?" He said "none". I asked him, "why would you want to add an obsolete $500 chip to your collection if you don't even have any of the current $100's?" His answer was, "Good point; I guess I'll pick up the dozen current A.C. $100's this weekend."
