The face is raised more and more full features on the Lincoln. The revers is as normal. Looks to be AB grade so I don’t know how wear would happen to only one side with the condition of the coin. Let me know why, thank you. (Pic compares to normal AU coin)
I think what you are noticing is the difference from the 1969 Die Recut. Pre 1969 cents seemed to have a high relief compared to the post 1969
