Only if it is a Mint Mark. Could be a plachet flaw or old damage that only looks like a mint mark. But I don't think it's a MM. Let me try @Rick Stachowski Anything of interest?
It doesn't look like a mintmark to me. It actually looks like a bubble bursted and left that looking like a mintmark. It is older and worn.
Not sure how a bubble could form of a die, Although it does seem to look like a D I think it is damage and is simply displaced metal.
IMO it's not a D. Whatever made the impression in the center, pushed the other metal around to form a rim, and it just coincidentally looks like a D.
not similar at all What you have a zinc core lincoln cent. They are very susceptible to minting problems and later circulation problems. In this case the mint mark is imploding from corrosion. Look up (a) split plating; (b) plating blisters; (c) occluded gas bubbles; (d) corrosion domes and you'll learn a lot just from that. From mid 1982 to current they changed the composition from basically mostly Copper to mostly zinc with a thin 8 micron copper plating. The mostly zinc composition ends up reacting with the copper plating and creates corrosion when exposed to various compounds ... So any break in the surface can start a corrosion process in other locations on the cent. Your cent has several corrosion spots. here I circled in Yellow the major corrosion spots (in various phases of corrosion) on your cent. The Die Deterioration long spot looks like it's corroding too. fyi, it is always best to start your own thread.
