Take this with a grain of salt as I don't really know how to grade myself (although I wanna learn), but I read that a grade of 70 is supposedly "theoretical" perfection, and that it isn't used. Now obviously there ARE 70's floating around, but maybe like kuh said, ICCS subscribes to the thought that there are no "perfect" coins. It's what leads me to believe that he's on the right track with his line of thinking.
