I found this in a roll of pennies I was going through I noticed it right off hand. what error is this exactly? And what's the possibility of this being found again in circulation and potential value?
Looks like someone took a belt sander or angle grinder to it. Doesn't look like an error. Hard to tell from the pictures provided. If you can edit, please when you upload the pictures choose Full Image rather than Thumbnail. , Also, cropping (trimming the picture so you only see the coin and minimal background) and being in focus helps us help you. Thanks
The edge is very smooth I worked with both Sanders before and I don't know if one that can leave a finish like that?
The cause of the damage is irrelevant. Maybe it was a sander, maybe it was something else. The IMPORTANT question is - how could this occur in the minting process. And the answer to that question is - it can't. No sense debating the cause of the damage. Like anything new, it takes time to learn and understand the minting process, but if you're going to search for errors, you really need to put in that effort.
