This coin looks like a piece of string might have gotten on both the hammer and anvil die, or it's just PMD. The depth of the score is pretty consistent, making me lean more towards struck through than PMD. What do you think?
I've seen this on some of my coins and turned out to be corossion on top of a scratch. Not saying this is that but resembles them. I noticed some paint or something of that nature was cleaned off both sides up to your marks in question. I'm curious to find out what it is for sure. Cool looking for sure!
Kinda looks like a planchet issue to me. Almost like a lamination at the portion where it is across Lincoln's chest.
Your coin suffered a lot of environmental damage. There is a very high likelihood that whatever caused the corrosion and color change also caused the other marks.
It's not raised so not a struck through. Looks more like a planchet defect that has been affected by environmental issues. There is corrosion in the coin, not on the coin.
