Since Lincoln's collar looks unaffected and the groove seems to go "underneath" the portrait and pick up again on the other side of him, it looks more to me like a planchet flaw than a strikethrough, but then again, looking at the date, I'm not so sure. I do think it is a mint defect of some kind rather than post-mint damage.
Could it be a die dent? It has that same rough texture. And like @ziggy9 said if it was damage there would be zinc showing. (image courtesy of Coinworld.com)
I see a strike though...like a medal spur that for a few strikes stuck to the die,transferring the shape onto the cent. The lines running up in front of Abe face seems to been a part of issue also.. worn die from strikes as well FO in the chamber .
It’s called a field restricted strike thru Google “errorref field restricted strike thru” That’s a nice one at that great find
The field restricted strike thru occurs when the feeder fingers that are guiding the coin into the striking chamber scrap along the die face with a bunch of grease and gunk on them and that gets smeared onto the die face causing what we see here. It’s rarer to be seen in both sides of a coin. I’ve got a 2019 with a major field restricted strike thru on the obverse and a bit on the reverse.
So feeder finger damage leaves these fine lines at first it scrapes along the die face so it’ll only go on that not into the incuse areas hence it looks like it’s going “underneath” the portrait of Lincoln. Now what we see here is a field restricted strike thru. Grease and crud got scraped along the die face if there’s enough it’ll effect the incuse portions as well if the portrait (Lincoln)
Thanks for the correction on my attempt to identify Amberlarry22's cent, good to know. Heard of and seen examples of strike throughs. "Field restricted" defines it even further. Will add to my ever growing file of error definitions and types.
