A 1,075 yr old coin?...certainly, you don't often find these in the wild and...oh wait a minute...uh, no, it's just a brutalized cent, likely 1945, eh?
Just a gouge, so damage, not an error. Who knew Abe Lincoln was a time traveler who visited the Byzantine Empire in the 10th century? Cool!
Just a suggestion.. We do have a Error Coins forum. Ask your questions there. First find out if it is an error or not. Then worry about value. Most minor errors have little or no premium at all. Peace
Start your own unique separate thread. What you just did is considered hikacking. Post pictures also. Try the US coins forum.
