I'm posting this in response to a recently posted 1957 Lincoln Cent by MintedNotPrinted. Both coins show one strongly struck side and one very soft side. This effect can be from a one-sided acid bath, but at least on this one the opposite side would suggest that a thin layer of lamination was lost after the strike. For now, I am not 100% sure on this coin and still pondering it as I just found it two days ago. Weight is 2.66g and diameter is 19.0 1958 Lincoln Wheat cent mint error - split after strike   |

That's a very cool example, tropicalbats, with the split on either side. I'll definitely be weighing mine tonight...
Thanks for posting!

very cool cent TB, but do you think that the reverse side had pate on it as it was dipped in the acid, thus protecting most of the design elements?

I've thought of that. Seems reasonable but the coin does not seem to be out of round with thinner rims where the surface is removed than in the areas where it is well-struck.

A very interesting coin TB. The lower left portion ion the reverse resembles a lamination that fell off post strike.
I have no idea why the obverse shows such a weak strike.
Take a look at my other hobby ... http://www.jk-dk.art |

I should think the upper right portion of the reverse also resembles a lamination that fell off post strike. My thought is that the entire obverse lost a thin lamination as well creating the soft strike appearance.

Lost lamination seems like a good bet. The reverse alone can't account for a missing half gram of material.

To me the lam loss of an entire obverse and partial reverse would drop the weight more than half a gram. I'm thinking PMD but maybe not acid. The area just east of the "s" in pluribus might hold so clues if we could get a closer look. It looks discolored there consistent with the "loss" areas. |

Still can't say one way or the other on this thing. It's odd and just won't fit neatly into an answer.  |

Very strange. I would think somewhere along the seams on reverse there would be some evidence of lifted/peeled metal if it were a typical lam. The uniform depth of the obverse and reverse "loss" areas seems a clue to me as well. Large lams tend to have uneven higher and lower grooves and chunks missing. It looks like a missing clad layer error but can't be, so I'm still thinking PMD. Thanks for the additional photo. "Pride is yoked with callous behavior, as humility is with compassion."
