A clipped coin aka incomplete planchet sometimes shows a diminishing on the rim that is opposite of the clip. The rim is not formed as strongly in that spot. This is because the punched out blanks go to an "upset" machine that forms the rim. That's when the blank becomes a planchet. But the machine does not have anything to push against where the clip is, so less pressure is delivered to the opposite area resulting in a diminishing of the rim or the Blakesley effect. So named after the person who discovered it. However, sometimes there is no Blakesley effect which makes it a mystery again. I don't see it on your dime. This may be because your clips look more straight than curved so the "upset" may have been able to send enough pressure to the opposite side. Do you see anything?
That's not an incomplete planchet unfortunately. It looks like blunt force to the edge A true 'Clipped' planchet wouldn't show reeding in the area in question. That means it was perfectly round from the time it was struck. But great that you ask!
Anyone care to revise their post or explain to me how this is not an incomplete planchet with a small double clip? The second photo clearly shows a copper edge. Yes there is reeding and there shouldn’t be but it the clip was so close to the edge couldn’t it allow reeding along with the copper to be present? Look at the last photo. The surface of the coin but the one clip area is raised in the field. Damage would cause that but I also think the minting process would do the same with the clip being so close to the edge. I included my Kennedy Half Dollar triple clip to indicate what I’m referring to but the clip on my coin is much larger than that of the OP’s coin, not to mention the size of the coin, a dime compared with a half dollar. Someone please explain. @paddyman98
Looking at the bulge of the surface behind the flat parts it looks like someone hit it with a flat surface/hammer. But I'm no error expert, but years ago I fiddled around with duplicating "errors" with non-error coins. This one looks like it can be duplicated as there is no control over the material behind the flat spots (ie, when it is in the die press that spot should be flat based on the 3 dies). I wonder what the reverse looks like.
This is the age of clipped coins, not clipped or incomplete planchets, these coin were stuck on a roller press then punched from the strip of metal. I will look to see if I can find the coin to show what the third side looks like. You won't see reeding on such a shallow flat surface. I am looking for a strait clip edge to show.
Sorry. I'm with @paddyman98 on this one. If anyone knows, it is him. If you do believe it is an incomplete planchet error, then I would have someone qualified to look at it firsthand.
Definitely not a incomplete planchet, curved or not the reeding would not be present. I am haveing the hardest time finding one of my end off roll, or edge or roll clips, the collar doesn't implement reeding.
The reeding on the clip that goes past the ear does not look damaged to me. How is that possible if some kind of force was used against it? I'd like to see how that reeding compares to the reeding in unaffected areas. Something just ain't right about this. IMO.
