I think what you are seeing is called a ridge ring. Common on zinc cents https://www.error-ref.com/part_iv__die_errors/
Thank you guy's for the information on this. I did go to error.ref before I posted this but couldn't find anything that looked similar. Again, thank's, now I know...
Not a lamination at all. It’s a ridge ring and that’s caused by a worn die. If it’s on both sides then both of the dies are worn.
Aha. So "ridge ring" is the term for that. I've seen 'em, but was not up to speed on the terminology.
A ridge ring looks like a rim on the face of a coin, usually into the letters or design of the coin. All because of a tired, worn out, over used die.
