1983 D Over S Lincoln Penny ? What The Heck

I also just found and ruined one because I thought it was just dirty. After cleaning it. (I know I shouldn't have.) But now there is a whole where the D was at. Buuuuuut now that it is clean. I can clearly see a S behind the 3 as well. This is my first post on here if I can figure out how to post a picture with this I will. But for now I guess people will just have to take my word for it.

But mine had not one but 2 S marks on it. No w only 1. But it's clear as day now. If your wondering how I cleaned it I just did a simple soak and rinse with diluted citric acid in water, then I pat dried it with a micro fiber cloth. I know they say don't clean coins but this one was covered in something that could have potentially been harmful to the coin. So I gave it just a quick rinse. No scrubing no toothbrush. Just a rinse.

This site doesn't really allow quality images I used 5he app perfered. And that's the best quality I could upload. But trust me on screen it's much more obvious. Just for Giggles I made one copy of the image using negative properties of the original image and it actually blacked out the three and really highlighted the S. So much that it was honestly funny to think I have people telling me these coins don't exist.
