If you can take a clip from the side at 200x or better, could show the fragmentation. Strange damage, so please take this side photo. Some times the melting process form inside the liquid metal drops of impurities which do not side up. Then when the lamination is done those impurities are up. Also do to the fact of lamination, the structure of the metal is enlarged (molecular structure). If not re-heated to come back to normal molecular structure, when other forces will be applied will cracks or simply separate.
I analyze many coins from the point of view of the alloy or metal, I do not collect errors or varieties. Many we thing it is die error, but in fact was only material lack of proper striking condition.
Your coin have a strange broke part. For the first view I we say: On struck, under the pression the agglomeration of impurities make go apart. Side view will tell us everything.

It looks like damage and ensuing zinc rot. Spend it.  In Memory of Crazyb0 12-26-1951 to 7-27-2020

Not an error of any kind, just zinc rot.

Coop has a great photo that explains clipped planchets. I'll see if I can find it.
Correct me if I'm wrong, but clipped planchets will have a straight line or very close to straight. They won't be a jagged break like this example because it's actually that the planchet was cut at the edge of a sheet. Am I remembering that right?

Alright, I almost got lost in Coopapedia, but I made it back with that image for you and some more information. This is the straight clip I was thinking of  What I learned more about is the curved clipped planchets I mentioned as "very close to straight." Those happen when a cut is made in the sheet that overlaps a previous cut (think about punching holes in paper and not moving enough for a full circle on the next one). Edited by IsThisAnything

Thank You! I read that also. Most clips have a smooth edge. Okay - back to the hunt!

OK, correcting once again: coins can also have "Ragged clips". Please read for more information......... http://www.error-ref.com/ragged-clips/With this said - your coin is NOT a ragged clip - just damage. |

The real clue for telling if it is a mint error or not is look at the area. If you see zinc, then it happened after the strike. If it show plating the same color as the coin, then it is a real deal.  Real error, or faked? Take a look at the images of this coin. You will remember this clue when you run into this again.Edited by coop
