UNUM looks strange though
The one thing I learned from examining proof coins graded 69 & 70, is that it only takes a very small flaw, no bigger than the size of a pinpoint, to lower a grade to 69. I can see this with the coin in hand, but for me, it's impossible from a photo.
The Mint has perfected their production methods for proof coins so much that now the only ones that carry a decent premium are those that grade PF70UCAM (or DCAM).
That wasn't the case in 1971.
That is true, but the grading services, today, aren't using the standards that were prevalent in those days.
