I don't think it is. It looks like it might have been ground down maybe by some kid rubbing it on the sidewalk.
I'm no expert, but it looks clipped to me. Not only because it's a perfect, straight cut line that's consistent with a clip, but the color and patina are the same as with the rest of the coin. And there's no other surface damage to the coin...if the coin got caught between moving parts or a piece of machinery that would be able to grind it down like that, I would think there would be other surface damage...IMO -LTB
I'm basing my opinion on the fact there is no Blakesley effect. The opposite rim is even. Again, just my opinion.
Can you take a close up pic of the edge where the clip is? Here's some pics of a confirmed clip, compare them to your coin:
Tough one. I certainly wouldn't hold the Blakesly effect on a clip this minor as the ultimate judge, but as Abe pointed out, seems a little weak opposite.
Thanks guys, I could'nt get a good close up of the edge. However it does not look like badthad's close ups, most likley ground down. I have another that I need some expert opion on, since I know nothing of error coins. Is this enough to be called a double die?
It sure is, and one of the nicest examples of Class 5 doubling in the Lincoln series. Unfortunately there were a lot of these minted, so value is not as much as many of the other doubled dies that are this extreme, but it's still a great find!
on the op, 1) Not a clip (if anything) it would be the end of the strip. A clip is round. 2) I don't see the Blakesley effect, altho some see it, I don't
