I sincerely apologize for the shoddy photography. I've given up on getting my microscope to work and have lent out one of the cameras I use for this, so these will have to do for now. Please give me your input on the coins. Thank you! Item #1 1992 D Lincoln Cent The D appears to be smashed into the coin. It's lower in relief than the date and if I had to guess, I'd say it's a D/D RPM (look at the bottom right of the D to see if you agree). I also see small doubling on the top of Lincoln's head, by his hair. I don't think my photos captured this. If you can't tell from the photos, that's fine; I'll get better ones down the road. Item #2 1980 Lincoln Cent Possible doubling on the Liberty and In God We Trust. Likely just MD, but I wanted to see what you thought.
On the 1992 I see possibly the start of zinc rot or something else on the "D". It can't be a RPM since they stopped hand punching the mint marks in 1989. On the 1980, all I see is MD.
I do see the Zinc rot... No thoughts on the D being thinned, shadowed by a curved line below it (look at photo 5) and sunken comparatively to regular mint marks? I know it can't be an RPM, I think it's actual doubling. I know the photos aren't doing much justice, but there's a clear second line above Lincoln's head that suggest MD at the least.
I respectfully disagree with both of them showing machine doubling. Please explain how the 1992-D exhibits machine doubling. And while I thank you for your input on the coin values, I'm not concerned about their value. I don't collect for investing purposes, I collect because I think coins are cool. These two coins stuck out to me so I'm trying to see if they catch anyone else's eye. I think the 1980 is very likely MD, but I'm not done with the 1992-D. I have looked at tons and tons of Cents and this one is strikingly odd. (pun unintended)
