Got this one from another error collector. He thought maybe it was some kind of cast copy, but I'm thinking it was sandblasted. Neither of us have a clue how the odd incised shape got on the reverse. Just one to ponder over. 1934 Lincoln Wheat cent damage - ? 2.79g

Wow, that is strange. I would think it has to be struck through as there's no distortion on the obverse. The sandblasting is just sad.

Would be interesting to know how it was done,but it is PMD not an error IMHO. John1

Seem to be cast on sand pads which was not dry complete(goldsmith way).

I do not know about the struck thru. on rev. but the texture looks like maybe buried with rusty stuff?

I'm warming ip to the sandbasting possibilty, with a dose of acid perhaps. That, along with the strike through--or maybe cut with a directed jet of sand blast.

Quote: Another 'Struck through an Earthworm' That poor earthworm... But nice struck-through 'something hopefully not living' and maybe the coin took an acid bath afterwards to get cleaned up.. VERY nice find TB. thanks again for sharing.

Looks more like an acid bath. (Short bath/lower acid bath, that didn't remove as much of the metal) May have been done to try to cover up a PSD coin? If so, then the edges would be also altered? I can't see this as a mint error with the reduction of the weight and the texture.

I had thought of acid as well, but the surface looks more like a million little hits not a bit of dissolution. Of note the coin does seem to still have pretty strong rims, but a micrometer says the diameter is 18.9 so it is a little off there. The edge shows the same kind of million hits texture as the top surface.

Here are some photos of the texture of sandblast. I still stay for casting. The acid for cooper must be mild acid to do such things. The flow of the metal on the reverse tell me was cast with the point of flow somewhere on south part. This is characteristic to casting if the melted metal occur in humid casting base. And this was not centrifugal casting.
