Is this an error or PMD?

Sorry but it's not easy to get a pic of something like this. Basically on the front side, one one edge, you can see that some of the penny is raised and the edge appears "broken". The back looks fine. You can see in the pic "in" is completely in the raised area, and it wraps around half or so of the face of the coin.



EDIT: Forgot to mention that it's a 1989 plain cent.

It looks to me as the typical poor plating that a lot of the Zincolns seem to have.

That seems entirely likely actually, thank you!
