It's possible it is a post-strike delamination, but I would expect some of the reverse design to show through, even if just a tiny bit. The ridges are fairly regular, as well, leading me to believe that it was intentionally tooled/machined. Maybe someone started to make a Magician's coin and gave up.

I do not think the mint even waffled coins way back then. It looks like some kind of PMD. Maybe Mike would like to see it? John1  |

I'm no expert, but isn't that pattern awfully regular for a split planchet?  |

 Note how the edge is not as deep as the trenches? If it was done by machine, then that would not rise near the edge. The compression of the strike on the edge must have prevented this area from not being as shallow as the center as the coin. Also if it were machined, it would be smooth. Not showing pock marks in the affected areas.  Edited by coop

There is no way this is a split planchet. This was done by grinding. Hence the lite weight. It's to perfect to be a random split. There would be some of the design left ether pre strike or after strike. And as far as one side being left, it wasn't held square to grinder.

Seems illogical to me, but I don't argue with coop.  |

I've sent this coin to Mike for his analysis, will post results when I hear back from him.
Pictures are very hard to review, so an in hand exam by Mike I felt was warranted.
I truly appreciate everyone's input!
Thank you, thank you, thank you!

The ridges being perfectly even and symmetrical make me doubt this is a split planchet.
The obverse looks suspiciously weak too.

I think it was hit with a tile back groove cutting machine along the course of it's life, could also be done with a drainer groove cutter, could have been quite a few tools to do this but I think it was a long while ago in my opinion.
Looks way to mechanical and intentional to be a planchet split or huge lamination.

The mint didn't start waffling coins until 2003, according to Coin World. Show your financial support of the Coin Community Family (click here)See my topic on Mexican Numismatic Medals (click here) |
