I have read here that it is mechanically impossible to have a coin leave the mint like this. I agree the prior reply. Could two planchets enter the press at the same time and produce something similar?
I've seen photos of at least two error coins that had more than a dozen planchets fused together. If I recall correctly, Charmy Harker, @The Penny Lady® posted one of the photos. Chris
Half a Cent now The obverse shows an upset (raised) rim. The reverse shows a completely flat smooth surface. Evidence of a ground down coin. I'm sure it even weighs less.
Well yes and no, it could happen, but there would still be some impression left on the blank sided though quite obscured. I've seen slabbed pairs before. I believe Weinberg had them.
Sort of, but the resulting mess would show features which identified it as what it was. Some details would transfer, diameters would be weird because two coins won't both fit into the collar at once, and anyone versed in the minting process could tell. You wouldn't see a nicely-machined look as shown in the OP's images.
