1919 S Lincoln Wheat Cent Die Wear Or Something Else Mint Mark

It's not die wear.
Looks interesting, can you try to get a clearer picture of it?

I've tried that the best pic I can take

J Wexler lists two S RPMs for that year, but it's neither one of them: http://doubleddie.com/902255.html

With all of the scuff marks it's difficult to tell if it is an RPM or just damage. I suggest talking to John Wexler about it, maybe he would be interested in seeing the coin in hand.
His email address is listed at the bottom of this web page: http://doubleddie.com/1801.html

My vote is a hit from the south west chopping the upper loop of the MM pushing it up and raising metal under it and the downward raise from that one as the top of the S is on top of that raised metal

I agree it looks like damage to me. If it were a RPM, would have been more listed/found of a die this obvious.

I'm still leaning toward RPM here.

1. When I enlarge the mm photo, I don't see any obvious damage to the areas of the primary mm that would give me comfort explaining the metal to the North. The only serious damage is to the outside curve of the lower loop, and that metal wouldn't have ended up north of the upper loop. in fact, the damage to the lower loop looks to have deposited its metal adjacent to and at the top outside of the lower loop.

2. What I do see that intrigues me is what appears to be a light curved line descending NW to SE through the middle of the top loop of the primary S. I can't explain that one with damage, and it is about where the descending curve of a north secondary S would be found.

3. I also see a horizontal line through the bottom loop of the primary S that could (and I emphasize "could") be the return of the bottom loop of a secondary S. That's close to the damaged area, and much better photos would be needed to be sure.

There are still some unlisted RPMs in the early Lincolns. My 1916-D with the D/probable D East/definite tilted D Southeast is readily apparent, but hasn't been listed either. I can't explain how that one has hung around unnoticed for a century.

I pawed through my 1919-S junk box last night, and couldn't find anything close to your coin. That doesn't add much to the discussion, because my junk box was pulled from circulation in the 1960's, only has a hundred or so coins in that box, and most of those are shrapnel. My two higher grade 1919-S cents are boring, with clear, plain mint marks.

Back to your coin, Wendell, I think sharper photos are essential. This is one that I would send in for attribution. There is enough possibility here that it would be worth it.
