Definitely get "The Chip Rack" and or "The Official U.S. Price Guide". These books will help in determining the value of a chip in relation to its condition. Also, look for a local chapter of the CC&TGCC in your area where you can meet some fine people to help. Go to www.cctgcc.com. I interpreted your request for guidance in the broadest sense (sorry if I misinterpreted). I had to find these on my own 3 years ago.

BTW, how do you put those cute little yellow faces at the end?
