Is a lamination possible on a plated cent? No, I completely missed the date.  |

I have been still puzzling over this. I tried a photo at an angle. It appears that the field to the SW of this feature is raised higher than the field to the NW. This is leading me to think that it is a bi-level die crack. What am I missing?  |

Looks like it is raised because of split plating? I see zinc in the last image. What split it? I'm not sure.

I don't this so as a die crack is incuse. An incuse line on the die would show as raised on the coin. But circulation may have split the raised crack open exposing the zinc making it raised?

Thanks CM - I understand the message now. Of course I know that...and it produces a raised area(line) on the coin. It may be perspective and/or light/shadow plays, but in the last image I posted, the arrows sit on an area of the field which appears raised - higher than the area on the opposite side of the crack/line. I don't know what is going on between the last arrow and the Memorial top, but it looks like zinc deterioration to me.
So I continue to lean in the direction of thinking that this is a bi-level die crack.

I don't think it's a bi-level, Pete. If it were, you'd see more zinc/rot. I believe the area you're seeing as raised is plating pushed up from oxidation underneath. There is no displacement due to the crack.

It's a 93-D Bizzaro Crack.  |

Zinc rot alters the coin.  Note how the split lower SE on the mint mark start to rise at first. Sometimes it collapse in. And eventually the mint mark can fall off. Just part of the process. |
