Here's a better pic, same coin as the top pics above but different lighting to show the direction they're bent.

The obverse is pushed out/up and the reverses are pushed in or slightly capped.

Most of them are bent like this but a few are nearly flat, none are the other direction and all are centered the same and from the same die pair. As you said on the rev part of UNITED is missing but on the obv L of LIBERTY is right on the edge.

None of them have any strike doubling. I just counted them and there's still over 20 and they all came from 3 obw rolls. In the rolls I could see them because the thin sides were cutting the paper. Very Happy

ED, it looks like I might not have understood the explanation that they have in the book, and in an earlier post. I still am not sure how the obv could be up, and the bend also be up....but again if the obv is up, (as it should be, normally), then the collar is what caused the "bend" in the coins, when they were struck, "the second time", driving them down, back into the collar, and casuing the bend. check the edges to see if there is any indication of a second strike, "on the edge".
That would be the result of a partial-coller-strike. I have never seen a coin like this, (these), and until you sent me one, I had no idea how it could happen, until I read the Plaid Book.
BTW, did you send one to Coop? He might be able to explain this. I agree with you, and still have questions as to "how"!
The photos are as good as I have seen, and they sure show the angle, very clearly. One day I might learn how you do it, if I am here long enough! I am going to try Photoshop 7.0, to learn with.

From the look of the one in the pic it I don't see a second strike but it seems like the collar came down onto the obv from above it and pinched the planchet right next to the date and it bent as it was struck.

I think you're right, they are partly out of collar, that fits how it looks.

ED, thinking about the "mis-alignment", that had to occur when the coin was partially IN the collar, and partially ON the collar. That would laterally displace the reverse.

I think we are on the same page. What happens, is the feeder "puts a planchet in the feeder mech", and it slides it to the chamber. The planchet "falls" into the collar, where it is struck,. Then the lower die raises the coin up, (ejects it) and it normally would go to the collection chute. But if it for whatever reason is not ejected, it can't fall into the collar again, because it is too tight to fit. While still there the upper die drops, and the coin is struck again, and driven into the collar, but it being too large, is driven partially into, the collar, and ON, the collar, which causes the bending seen on your coins. Looking at the photos, again, I notice that the date is intact on one, and the "slope" seems to be downward, without any damage to the area. Another photo shows the date with obvious damage, and a possible "ramp". (my coin is this configuration). These two cases follow what they say in the "book", about the latest presses can and frequently do have the dies on different places. The rev, (normally low), in the "up" position, and the obv, "down". This is quite a change from the norm, to say the least!. Under these conditions, there will be no displacement, thus no doubling, albeit, the coin was struck twice, (or more times), as noted in the book.
