1943-D Mercury Dime, Variety Hunt RPM Miss (PCGS MS-66FB).

RPM or not it is still a beautiful coin.

with Spence - had you showed that close up alone I would have said D/D RPM.

Appears to be it, Stage C judging from the pictures, also has the same die crack near the wing tip. Excellent pick up!

Very nice RPM D/Inverted D Southeast. FS-501

Are you sure? When I compare it to the three examples on PCGS, I see some subtle differences. I put a certified version on the right, it's the middle coin from this PCGS page:

First, the D on my coin is shifted considerably left. Look at the gap to the stem. Also look at where the leaf tip is relative to the left edge. On mine, it looks inside the edge. On the certified version, it is to the outside.

Second, the position of the inverted D seems much higher up on the certified version.

Third, the obverse die crack seems to be at a slightly different angle.

I know that Die Deterioration can really change surface features. I also know that slight variations in camera angle can seemingly change where features appear to be relative to each other. Can this really be FS-501?

I neglected to compare the MM location and sure enough it is not a match to FS-501 MM location but it is a D/Inverted D Southeast

I do not understand this statement. A rotated die would have absolutely nothing to do with the mm placement or where the die markers would be. They are on the die, they would not move out of conjunction with the devices.

If I were to send it in, where would I send it? VV, Wexler, CONECA, somewhere else? Do the attributers even evaluate coins in slabs?

Of the recent coins that I took pictures of for Wexler, there were seven of the 32 coins in various third party slabs, so I would assume so but maybe email Tanner or contact him on this site, (Tanman2001). Here is the link for Wexler's coin examination, scroll to the very bottom for Tanner's email.
