From what's showing here, it doesn't seem like the lines across lincoln's hair or the letters on the reverse correspond to other design elements 1:1. If you have image editing software that can do it, try doing an overlay to see if any of the oddities match up with any points of the coin's design exactly.
If one coin had been struck and got stuck in the press when the next blank was fed in, the previously struck one would have raised secondary elements from the die face and design elements on the reverse would be flattened out due to it being struck against a blank planchet. In this sort of case (brockage if the previously struck one stuck to one of the dies) the blank would wind up with images of the same die (obverse or reverse) on both sides of it, one a positive image from the actual die, and one a negative (and weaker) image from the impression of the already struck coin. The only way I can even think something like this would be from a mint error is if this coin was struck, then two others were struck, and they were stacked together for a 4th strike, with this one in the middle. I don't even know if the presses have the clearance to be able to wedge that many in at once, and you would certainly see heavy deformation of the rim due to not being in collar and being struck between a couple other coins. Plus they'd have to be perfectly stacked to not be bent as well by the pressure exerted on them. I may be off on some part of this stacked idea, by all means Mike or someone who's dealt with more brockage examples than I have step in and correct anything that's inaccurate.
*e* Oh and if it was a die clash the clash marks would be lined up relative to the other side of the coin, the line on lincoln is way too far off angle for that to be the case. That and to get a line that deep into an element of the die as recessed on the die as lincoln's head is, the reverse die would have to have an element raised far beyond the tolerances on height of raised elements that are currently used.
Like I said, maybe off on some of this, but hoping to give a detailed enough explanation that the OP will have enough information to diagnose damage versus an actual double strike/die clash in the future.
It's pretty clear from the lines on lincoln's cheek at different angles (2nd post, first image) that this thing was heavily damaged once in circulation. Could have done some time on a highway with as mangled as it is, and the similarities of impressions to actual elements of the other die on each face are more than likely coincidental for the reasons noted above.Last edited by NearDateHound; 07-16-2010, 05:49 PM.
