The best thing to do, Jim, is to e-mail me with corrections or additions and, if you have a scan of a chip that is not included in the Visual Chip Rack, you may e-mail that to David. You may, of course, post the changes/additions/scans right here, but I may not see it as I don't monitor the board all day. I try to completely scan The Chip Board as often as possible, but if your post gets pushed down too far when I look it's possible I may miss it.
Also, if you include the circumstances of your acquisition including the price that you paid, that would be of additional help, particularly with chips you may feel are scarce.
