Check out the rest of the other coins he has for sale, quite a bit of clipped coins.
Some of those raise a flag for me. I just need to see better pictures to make sure if its genuine.

It could be a corner clip (aka assay clip), but doesn't it don't like the damage opposite the clip like it could have been held when it was 'clipped'?

Its a curved clip. the angle is due to the metal flowing into the "B" of LIBERTY instead of outward with the rest of the metal. the ribbing on the blakesley effect is due to the edge of the coin flowing over where the rim is missing.

I don't know the first thing about Mercury dimes or planchet clips... but I do know a bit about other things.... this is indeed a curved clip.... the B in LIBERTY has very little (if anything) to do with anything..... it is a minor device (not unlike the corresponding lettering on the reverse) which does not absorb much metal displacement. The reason that the clip looks as it does is due to the proximity of Liberty's cap, which is the most major device on the coin, (coupled with no corresponding device on the reverse), and as such, draws the lion's share of metal displacement. The effect displayed exactly 180 degrees opposite the clip is due to the upsetting of the rim.... while being upset, the planchet inherently was out of kilter in rotation in the upsetting machine, and the rim did not form on that area, because of lack of opposing pressure from the clip.... (imagine rolling the coin...same thing)..... the trailing away of the rim is mirrored in both locations.   Edited by zeewool

Thanks all who responded.
I still have a lot to learn about making of error coins.

It is interesting that the seller has such a high number of clips.

Strange looking Blakesley's effect. Never seen one ribbed looking like that before. The Blakesley Effect doesn't always manifest itself the same way every time - sometimes the upsetter gets it more "right" than others, sometimes it doesn't show up at all. This coin's opposite edge was strong enough to contact the collar with enough force to acquire reeding, and I think the clip might have allowed the planchet to tilt a little in the moments when the dies weren't at maximum travel, allowing some of the reeding to be impressed over the edge of the rim.

Thanks SuperDave, that makes sense.
I wonder if someone sold off an incomplete planchet type set?

I am not really clear as to how this came to be (meaning the process)?
I was thinking of bidding for it and keep it to study/references, but I want to have the expert here to clarify that its genuine.
Thanks Dave and zeewool!

The "expert" would be Dave..... but even I can say with all certainty that yes, it is most definitely genuine.

It's a righteous clip, an undeniable point of research interest, and I tell you plainly you might be competing with me in the bidding. |
