Two thoughts about these two sentences. First, you should (attempt to) explain this philosophy to Doug over on Cointalk. He is easily the biggest offender of these two things that I have ever encountered on the coin forums. Second, don't you think that this information about "micro-grading" could have helped us reconcile the grading dispute on the recent MS68 Roosevelt thread?
I'll pass on your suggestion regarding trying to explain the philosophy.
I don't think that a discussion concerning micro-grading would have necessarily made a difference in the recent MS68 Roosevelt dime dispute. To me, it doesn't matter if the reverse marks were man made or mint-made. Although the obverse is nearly flawless, the reverse flaws keep it out of the 68 category for me. I don't think one has to micro- grade in order to reach that conclusion.
I think you should reconsider, the entertainment value of that thread would be absolutely priceless.
I wasn't thrilled about the grade of that Rosie either, but I understand why PCGS graded it MS68 and I think that the holistic look of the coin caused the graders to overlook the impact of the reverse flaws, even if they were too severe for others to overlook, including us.
