My initial guess is "Yes", but the wear and the fact that I cannot attribute it makes me wonder. This is another one for Axtell...
Yeah after staring at it again.. If the MM didn't exhibit the PUP at K4-5 I would probably say PMD on that mark. But then again it's just a real tough one to call..
What is K4-5?
Think of a analog clock.
12 - Center Top
6 - Center Bottom
Moving clockwise around the clock, you can use it as a position indicator, since the coin is round. Imagine the coin with hands that tell time on it..
Of course - that is my understanding of it.. So I could be totally off my rocker..:)
