Hi guys, so here's another coin I have a question about, I read that there is an error on the mint mark on the 1957 D wheat penny. I read that the D mint mark was stamped three separate times creating a build up of the latter two marks, leaving the first stamping to show in the middle. Having not seen a photo of this error before on this coin I really can not tell if the coin I have has this mint error, or not. As you can see the coin has been taken care of and appears to be in pretty good condition, it's still in the thick clear plastic protective holder which might make distinguishing weather or not the D looks right or wrong. But if anyone would like to chime in on this topic that would be great, and very much appreciated.
Thanks
