I know the Reverse is Doubled under the Thumb and I think I have a DD on Lincoln's Nose. What do you think?
Any doubling anywhere else? I would suspect machine doubling. Additional close-ups of other areas would be nice to determine which doubling this is.
I don't see how it could be a hit, no displaced metal. What looks like a die crack is actually the fine line in the coat. Posted a few more pics with a change in lighting.
I don't see the crack now. In the first picture it looked like it was going across the top of Lincoln's coat lapel, which would have ruled out it being a fold in the coat. Maybe just a weird reflection in the photo.
Looks like post mint damage to me, you can see the low point at the tip of the nose where the metal was pushed up into that ridge you're refering to. If it was a true DDO, that part of the nose would be as high as a regular coin.
