@Giwalsh, my initial reaction is always PMD, but I'm not so sure on this one. Could something with texture have been pressed into the obv causing the rev to get that flat spot? Perhaps, but enough pressure to completely flatten the design elements seemingly would have caused the coin be more out of round. With intact plating on both sides, a defective planchet seems more likely, but I'm honestly 100% not sure about that. Any chance you can post a close-up pic of the area including and near to the word IN on the obv? Your image gets pretty pixelated when I blow it up. Thx. "If you climb a good tree, you get a push."

Ok that is a *really* nice pic--thanks for posting that. I'm open for disagreements, but this looks like a defective planchet to me that was plated and then (mostly) struck. Other folks here are way more knowledgeable about this stuff--I'll be interested to see what they say about this one.
If you have a good scale, weight it please--perhaps this coin is on the low end of tolerance?

Pending the opinion of some of the more knowledgeable members, I'd have to agree with Spence. If the zinc planchet was defective before plating, that explains the intact plating and weakness on the reverse in that area. I've never seen anything like this- I'm looking forward to hearing what others have to say.  My only concern is the mass. I'd think that if a chunk was missing it would be a little more underweight. Giwalsh, is your scale accurate to the tenth or hundredth of a gram? Perhaps, though, the damage to the planchet only cause metal to be displaced, not removed. Edited by Numisma

It looks like the coin is out of round. That would indicate PSD. But we should have Mike look ar this tomorrow. |

I agree with coop. My first thought was PMD, because it looks out of round. John1  |

I am going to go with planchet error. Seems like there would be some zinc showing if it were PMD. Looks like whatever happened was before the plating. |

If the coin is out of round,it could not have fit in the coller as an out of round planchet. John1 Edited by John1
