I have a interesting 1983 D Lincoln Cent that might have possible Lamination Error on the Obverse Side. Also the Reverse side of coin seems to show possible spreading and notching. Please check out my pictures provided and leave any feedback. Thank you!
Looks like something was spilled on the coin and stained it. I'm not 100%, but I'm pretty sure that only copper cents can end up with lamination errors, not copper plated zinc. I'll let someone smarter than me chime in to confirm or deny that though
Looks like a coffee stain to me.. perhaps Folgers Decaf. There is no lamination that I can see on this coin, just a stain.
