~~~ asking the dealer at a show to please remove it so I can inspect it after having done so at an ANA Convention in 1992, where, upon returning home and realizing the thin protective layer over the inlay was missing... A few days later I called a California chip dealer who taught me everything I know about reading a clay composition, Paulson-type chip who explained how that happens, sometimes.

Btw, I never put a chip in a Mylar, either -- I don't like staples...
