I promised that I would report what BJ said about this. He also consulted with Mike Diamond. They think it is post strike damage - with a thin narrow apron of metal being relocated from the rim to the field. They did not say how this might occur.

from what I understand, mr diamond is a busy man. I bet he never actually saw the pictures.

I admit that I am having a hard time understanding the interpretation. I do not see anything along the rim where the metal may have originated. The rim seems equally as thick all around.  |

consulted with Mike Diamond I don't know for sure but I have seen the pictures and I just don't see that as PMD. |

Mike is the expert. If you don't think so check out the site he posts images to. http://www.error-ref.com/If is seem to technical, he is breaking down for us to understand. If you saw a specialist doctor, they talk over your head. Same with mike. Not to impress anyone, but to make it understandable. To him it is probably juvenile. |

expertise only works if one sees the pictures or the coin.

I don't remember the coin for sure. I just know that Mike and Bob knows what they are doing. Was this the proof coin a while back. If so I've already thought it was a PSD event if that is the coin we are talking about. But I don't think that is the same coin I remembered. The one I'm thinking of was a proof nickel. |

Please understand: I am not saying that I think that BJ and Mike are wrong in their assesment. I am saying that I just do not understand it. Their explanation did not include how this could happen or how they knew this was what happened. What do they see, specifically, on the coin that gives them a clue? The feature is around a significant portion of the circumference of both the Obverse and the Reverse. What do they see on the coin which explains this. I see no loss of material along the rim at all. If this had been just a small area, say 5 mm to 10 mm, on one side of the coin, then I could possibly understand. I can understand SsuperDdave's explanation: Quote:
What happens when a split planchet gets slammed into the collar by the strike? Could the edges "petal" outwards and get folded onto the faces? The other thought is a thin strip that got caught between planchet and collar I can understand Conder101's explanation: Quote:
it looks like the edge of the die (the corner where the field drops off to form the rim) may be chipping or crumbling. This fits closest to what I am thinking: Quote:And yet another option: Peripheral die damage: http://www.error-ref.com/?s=peripheral And this is basically what Condor101 is saying! I know that it is not worth all this effort, but I would just like to understand these things much better than I do!  Edited by Pete2226

That is why I explain what I see and help others to grasp it. Others may give just a yes or no answer.

I like the way you do it, coop. I have learned a lot from the forum. Your photos and commentary are great!  |

I would like to extend my apology to all it concerns, for my comment about Mr. Diamond might not have seen the coin because it was mentioned he was "consulted". I didn't know mikediamond was a member here. Of course mikediamond saw it. I should have known better.
