I was driving through Southern Indiana today and went through the town of Madison, Indiana on the Ohio River. It's a neat little town with lots of antique shops. In one shop I was directed to a cigar box about half full of old inlaid chips. I love when that happens. I took out the ones I didn't have. there were a bunch of "CA/AC numbered" chips. Is there a positive ID on those and how high do the numbers go? Any ID on the "PHR"chips?
