Good morning coin community. Today I'm posting about a 2005
Lincoln Memorial penny that looks odd to me. I believe that I may have already answered my own question, but I would like to know your thoughts as well. On the obverse of this coin, you can see that it is very shiny and clean looking but when you flip it to the reverse, it is very dull pretty much the opposite of the obverse. I assume it's environmental damage. Let me know what you think and have a great day..
