I am a new collector so I really dont know what I am doing yet (Which is a bit of an understatement). I bought the Official US Casino Chip Price Guide which has helped me a little. I definitely need to join the mentoring program. I bought 96 old AC chips. I have no idea how to grade them and was intending on cleaning them but have not done so yet. They are mostly 1.00 chips but a few 2.50 and 5.00 as well. Is there some place I can go on the internet that will help me identify the issue and has pictures? Or is there an AC Chip expert willing to help me identify them? Chips are Atlantis, Playboy, Boardwalk Regency, etc. Thanks, Judy
