Is this simply old age or is there anything slightly interesting about this 1916 penny. I haven’t observed one that looks like this one. Is it worth holding on to?
Almost certainly a dug coin. So yes, environmental damage. Worth keeping? Well, it's not gonna be worth a whole lot monetarily, especially due to the surface issues, but it's a 103-year-old cent, so yeah, interesting enough to keep, if you wanted to.
