I just read this very, very interesting article on the history of coin grading. Tom DeLorey, for those of you who don't know him, was actively involved in some of the early development of our modern coin grading scheme. In this article, he also talks about some early discussions of a 100-point scale. Take a look: https://coinweek.com/education/coin-grading/the-early-days-of-numerical-coin-grading/
I thoroughly enjoyed it. Over the years I've talked about most of it, excepting of course some of the details that only he and a handful of others would know. For one I never knew that anyone talked about a 100 point system anywhere near that long ago. First I ever heard of it coming up was with PCGS discussing it a few years back. And then again recently. Nor was I aware that DeLorey was directly or indirectly behind adding the additional MS grades as the newer editions of the ANA grading came out. I was of course aware that they were added and when, and I've talked about that many times. But I had no idea of his part in it occurring. Thanks for posting it Jason, as I said I enjoyed it immensely.
