I found these two coins interesting but I cannot get photos of the edge of the coin due to the slab. It’s all I can do to see the edge and I still can’t see what’s on the slab, which is on the edge. The first is a 2007-P MS-64 ANACS graded John Adams Presidential Dollar. The edge letters are doubled and both sets of letters, the original and the doubled letters, are both position A. The second coin is again, a 2007-P John Adams Doubled edge lettering but this coin has inverted letters. This is also a MS-65 ANACS graded coin. At least you can see the coins and their labels. Do a little research to help you understand the difference on these coins. It’s very interesting.
both were run through the edge lettering dies twice. https://koinpro.tripod.com/Articles/2007PDollarAdamsDblPlainFS.htm one looks like the top orientation, the other looks like the bottom orientation. exact placement of them will vary depending on how it went through twice.
The slab may prevent getting photos of the edge, but since it is a prong style holder the edge, and there fore the error, should be visible. It was much worse back in the "pre-prong" era. I remember many times looking at large cents/half cents in slabs where the variety wasn't identified, knowing what the variety was, but not being able to see the edge and not being able to determine if it was the common subvariety or the very rare one.
Considering the error should go all the way around the coin, and at least half of the edge of the coin is visible, if you can't see it I would suspect it isn't there.
I can barely see it in hand. No way can I get photos on my cell phone. The slab from the TPG is correct from what I can see.
