If there's money to be made, some people will swear by the fake, even when it's obviously a fake. On this old example, the tooling marks on the 8/3 are in your face.
welcome to CT. i really hope its the real deal. i would send it to one of the grading companys. until you do that i found a great picture online of the real and the fake versions. hope it helps.... the bottom part of the 3 in the genuine version picture is pointing at the S. good luck
I could see that in the original photo, but this follow up photo makes it pretty clear that it is a tooled 1948-S.
I knew a fellow who found a 1943S penny. He announced it would go on auction starting at $1.3M. He made lots of plans. He took to a local coin expert. He determined it was an excellent fake but a fake indeed. Somebody had taken a 1948S and neatly sliced away the left side of the 8. I offered him $1 for it
That is always the assumption I start with. That's what it usually is, but take the time to do additional research. It's definitely worth it. My new ICON is the exception. It is the second rarest find I have made and the first I could afford to purchase. It is a solid 1796 NC-2. The rarest one I found was the third known 1793 NC-6 which was written up in the April 2019 issue of Penny-Wise. I also just purchased another miss that turned out to be a mutilated common variety. These outnumber the picks by about 8-1 and I'm a pretty knowledgeable fellow within my narrow field of interest.
