Hello, it's been awhile for me, trying to find something worth bringing here for help. It is a 1922-D, but I don't know if it's the weak D variety, as it does have a strong reverse, and the Red Book talks about die #2 being worn, but showing a strong reverse. I've tried lots of pictures with different lighting, some also with no zoom on the microscope and some with full zoom. Hopefully you'll have enough. If not I will have to wait and purchase a camera/picture box of some sort to get better pictures. Any help would be appreciated, thank you!
I agree with the upthread comments, 1922-D normal die state.
I wonder if the obverse surface crud is paint. If so, it might come off with an acetone bath. The obverse scratches would detail it anyway, so there wouldn't be much downside to sending it for a swim. Just a thought.
