I vote partial missing clad layer. I highly doubt it is PMD because it would be very hard to separate the clad layer. |

I cant look at this and not think its PMD. Looks like it got jammed in a machine. IMO  Edited by Alexer

A machine jam will not typically break off a thick clad layer, this is not a thin layer of plating. Even if it did somehow manage to break off, you would see rough upturned edges on the cladding where it was sheared. The devices would also be mushy and indistinct if the cladding was separated post-strike. The appearance is entirely consistent with a pre-strike event. Look at coop's image and take note of the distinct difference in appearance between pre- and post-strike separation:  Edited by biokemist6

I agree. The clincher for me was the strength of the devices on the clad missing area. Good job everyone.

I think it is a nifty little error, not a huge premium but it certainly has value  |

I totally respect everyone's opinions here that's what makes this a great forum. But now that I've seen the obverse I'm still not convinced its an error. I have several good questions as to why..how? But I must be the only one, sorry bout that.  |

Pennyman007, explain to us how the devices were not wiped out by the machine jam as you call it. That is the determining factor as Coop said.

If it were PSD, the obverse would be disturbed. It would be pushed out where the opposite side was cut deep into the planchet. We see nothing like that on that side. So it had to happen before it was struck. |

A bristle from a rotating descaling brush was rolled into the coin metal strip. It may have been rolled in after the strip left the bonding mill, or it might have been trapped between the core strip and one clad strip as the two entered the bonding mill. In any case, the piece of "wire" split the clad layer. The wire fell out before rolling of the composite strip was completed, and so the groove was partially closed up.

Thats fantastic now I understand how it could happen. Knowing its an error is one thing but explaining how it happened puts things in prospective for all of us. Thanks mikediamond for your explanation. Its pretty hard to learn if you dont know how it could have happened. End of story Thanks everyone.

Lincolnguy....... Quote:So it is only part PMD? What do you mean? IMHO it is an error coin. After it left the mint ... more " might" have happen to it. If I had to make a life or death choice it is an error coin. IMHO it is worthy of an ERROR collectors Quarter collection. Errors are the opposite of MS101. I LOVE IKES ... I LOVE ERRORS |

Thank you mikediamond for the detailed explanation of the process and how this happened. I will note a bristle from a descaling brush on the 2x2 for future reference.

docfishn - thanks for posting this unique and scarce error. I'm glad I pushed it to the point where Mike had enough of my bull headedness and provided us with an answer.
