Is this mechanical/machine doubling ?

I found this 1937P with reverse lettering on Pluribus Unum that looks odd. Usually machine doubling appears flatter than this but it does not look like the typical DDR with thick letters and the dot looks normal. Any thoughts?

Yes...machine doubling. Looks a bit odd, but I don't think it's a doubled die.

Pretty sure this is machine doubling. I found several in the roll and they were all having the same twist to the date and MM and left side of the profile. Probably one of the strongest MD I've seen so far?

Coop,

I think you're right that it isn't a ddo since whatever caused it got the mint exactly the same as the date.

Still it's interesting and I haven't seen mechanical doubling with that same look. Ha Ha jokingly it almost looks like the dies were hinged and tweaking/smearing it as they opened... interesting!

Ed: I did find a few of these in the same roll.

Actually, Coop, the machine doubled coin you posted is a doubled die, and it's a strong class 6 doubled die. I, however, wouldn't have kept them out of the roll because of the problem with machine doubling. I typically don't keep doubled dies or RPMs that have machine doubling affecting the focal areas.

CD, After I saw your photo, ( which looks like an ultra-deep cameo type strike), my curiosity got the better of me, and I checked my "Official Errors Guide" for the exact reason for the "class VI" decision, and, after looking at it again, saw where the doubling is visible, albiet very slightly, but definitely on the bottom of the "3", left end of the "7", and very slightly on the bottom-left of the "S". Two things that are nice to have: good friends, and a good reference library! Regards, Dick

They were placed back into the roll, just wanted to post an image of my disappointment with those coins. I found 5 that were exactly the same. So I wondered if it was something that caused them other than machine doubling. All coins from that die pair had the exact same doubling.
