It is damage. They are called plating blisters. It is caused by air bubbles in the zinc under the copper plating. The bubbles tend to expand and contract inside the cent until they finally burst through the copper plating on the outside. This is very common on Zincolns.
It's not a mistake. It's the real deal. It's not just damage, it's major damage! Spend it before it dries up and blows away.
this is the most I ever studied and took pictures of Lincoln cents in my life anything is rare to me ..that coin weights 2.34 grams rings on wood like copper ..i need to stop posting .
keep searching and you will find something! Honestly, it is what YOU like! After all, it is YOUR collection, right? I have some coins that are probably literally worth 1/2 their face value lol but, I liked it so, I saved it! At the end of the day, ...it is the things that you find, & like..."and if you took the time to photograph them", then for some reason it caught YOUR eye. Staple it up in a 2x2 and put away and mark as "Plating Blisters". Then when you find another one similar in the future, you will know the correct terminology =D
