Welcome.
First, post sharp photos of both sides of the coin. That will allow members to offer opinions on your "1943-S" cent.
A few copper (really brass) alloy cents were unintentionally made at San Francisco in 1943. However, a great many counterfeits have also been made and the likelihood of having a fake is much greater than finding an authentic piece.
After collecting opinions of experienced collectors, you next option is to send the coin to NGC for authentication and grading. Until that is done, your coin is assumed to be counterfeit.

I learned something the other day about CT. I always thought that two different users could not have the same IP address but they can. Something like a father and son can both work off the same PC with different user names.
Fun story from CT. Father and son both have accounts. Father gets banned for some reason. Son still keeps posting. Father tries to use sons account to post on the site. Both accounts are now banned. The writing styles gave them away.  
 

I watched this coin change over 20+ years. I believe it was messed with before being graded. It's pretty ugly. 
 
 

Doug is a member there and probably here. Not sure when he posted last. Not really important. I'll guess that starting a second account on CT is what created the problem.

I agree with JP. Looks xf to me also. Lots of wear on the high spots.
