Hi Mary! I hope for your sake you really do have a 1943 copper lincoln cent. Based on how rare they are, I highly doubt it is one. Please show us a photo of the Obverse and revers (front and back) and maybe we can help you out.
Huge fake. Doesn't even look like a Lincoln cent. And if it is, the 3 is all wrong. There's around 26 of these, and yes I believe there was a recent discovery not too many years ago? But there are millions of fakes, and 26 reals.
That date is a huge tell tale sign that it is a fake. It is horribly misaligned and you can see damage to the date as well. Sorry, it is not a 1943 copper.
