Hi Pete,
First off glad you liked any chips you have received from me. Second that big list you attached here will never be anything to worry about as far as I am concerned.
Third, Yes! We made a brave move on rarity. It was a lot of research. It never ends, is the part I didn't think of. Everyday I add information to my files.
Our scale to grading was lots of thought. One main important one was that we did not want to see complicated "coin" grading. Have you ever seen the huge book on grading every coin differently? We felt if we put down some guide lines that could be followed that once chip collectors learned the grading system that it would be harder for coin guys to come in & lay down crazy criteria. Like the big ICG list! We felt it was not that complicated.
And lastly we aren't checking for fingerprints yet. We will skip right to DNA. I want to find out if Bugsy actually did touch my chips!
