I was searching 1942 Ds today and ran across the first example of the flattened 9 and thought it was a little odd, but obviously PMD (see the first two pics). Then I came across the second flattened 9 and it seems to have some interesting features. Note particularly the bottom part of the 9. This second coin is pictured in the 3rd and last pic. This second coin is also in VERY good condition. Thoughts?
To answer your question, I really don't see what you're looking at?? All I see is Damage and Verdigris. Sorry. JMHO.
The other marker already photo'd is the MM placement. These two coins aren't from the same die pair. The D's are in different positions.
Looks like PMD. Interesting how it produced the appearance of DDO. For help in attribution, don’t forget to include full photos of the obverse and reverse.

View attachment 1574057 What I have trouble with the PMD idea in this case is the raised edges on the bottom of the 9. Enough force to flatten a number should not leave a raised ridge on the edge of the area that has been flattened. View attachment 1574057
I see what you're seeing there, but I have two issues with it. First is picture quality, from that image I would be really hesitant to come to any conclusions at all. Second, and this is an actual question, how in the minting process would you get what that image seems to show? I've been peeking in on this thread, the idea that you have something there is pretty cool. Keep doing your homework on it and get it figured out. You've hung around here and paid attention as people have helped you. Pay 'em back and get an answer on this one!!
cwart your thoughtful reply is very appreciated. I'm new to this I have a lot to learn. I can't get any closer than with the pictures I've taken. This last one, with arrows, is just a blowup screenshot of an earlier one to point to the ridge. I don't know how the ridge could have been formed other than to speculate. It looks like a whole layer of metal flaked off, a majority of the right side of the 9. Interestingly the first coin also looks like this may have happened but the break is slightly farther down the right side of the 9. Perhaps something about the thickness of the 9 had something to do with this process during strike ? I'm thinking the chunk that fell off could have left the ridge? Metallurgy is about as far from my area of understanding as I can get..... but you asked for it. I'll keep hunting for a better explanation. Thanks again.
I am not seeing anything just a circulated old cent. PS Die markers are you key to attributing. Mint Mark position should be your first go to. Philly's can be a little tougher.
