I've had this Lincoln for over 40 years. I could never figure out how it got the way it is. My original thought was some kind of lathe or a screw down press. It's odd how it looks like the obverse and reverse rims are still kind of intact and there is mint luster in the flat spot.
PMD but how and why are the questions. My guess would be it was used as something in a mechanical setting, like a spacer for some equipment, but that's just a guess.
I can't think of anything that could occur during the striking process that would stretch the coin and leave the raised line on the right side. Going back to the old rule, "If you can't explain how it could occur during the minting process, it can't be an error." Almost looks like it got caught in a something like a coin rolling machine, but with enough power and spacing to shear the copper and push the metal. Just a guess, but I really don't know what caused the damage.
I dunno someone used it for a chair leg end cap or a table shim maybe for balance? it certainly is an odd one, but I think the call is correct, PMD because it's so out of round.
I suspect a cent placed off-center in an encasement ring pre-strike. During the strike we get part of the encasement ring design, part of the obv design is flattened by the center recessed area of the encasement die, and on the reverse the cent design is spread and distorted as it is forced into the aluminum ring.
Yes. the aluminum ring is put into the collar in the press, the cent SHOULD be put in the hole in the center of the ring but instead it is off-center, part in the hole part up laying on top of the ring. Then the press cycles striking the ring. It strikes part of the design into the obverse of the cent and flattens/distorts the part of the reverse that was laying on the ring. The center of the encasement die is a shallow depression that is supposed to keep from damaging the cent, but since the cent is not properly in the hole part of it get forced into that depression, makes contact with the bottom of it and it wipes out part of the cent design. That is the section that has wiped out TRUST the last part of the date and the end of the bust. Apparently it wasn't milled out too smoothly, but they weren't expecting it to make contact with the coin.
