It looks really cool, but I agree, its PMD |

Good questions eaglefoot...I'm anxious to see the answers myself. One thing I recommend to everybody is to get out there and experiment.try making some vise jobs or flattening with a hammer,etc...It's a good way to see the results first hand and helps in recognizing PMD later. |

Eaglefoot,
Just go to a hardware store and look at the work surfaces of a cross channel vise, or a roofing hatchet. Both items will have a 'grid' waffling pattern that is certainly very close to what you are looking at.

Don't need to go to a hardware store though...... I've spent 23 years in the construction business, and have used these tools MANY MANY times !
They would press "inward" and "into" the surface of the coin ......not "raise" the metal of the coin. This is what puzzles me with those theories.
And there would be marks and indents too......of which there are NONE.

To me it never really matters what caused the PMD, it's damaged and that's all that matters. There are literally thousands of ways a coin can be damaged, from vises to industial dryers, run over by a truck or beat with a hammer. While it's fun to speculate sometimes, I never let it bother me if I don't know what caused the damage. What matters is a good understanding of the minting process, so you can easily determine if something you have was even possible to be made at the mint. Dave Edited by Dave42

The person who operated the press let felt some kind of metal screen on the planchet etc ! If was PMD the features on the coin would be damaged by pressure or contact ! I'm not specialist but for me looks more real then PMD! |

No chance at all, the coin has been damaged by the pressure- look at the mangled rim. Quote:To me it never really matters what caused the PMD, it's damaged and that's all that matters.

It is a complete waste of time to speculate on how a coin was damaged as there is an almost infinite number of ways of damaging coins. However, there is a limited number of things that can happen to a coin during its production. When you learn what CAN happen, it is much easier to figure out what CANNOT happen. Edited by biokemist6

Just remember that telling somebody it is impossible doesn't really stop the wheels from turning unless they understand the "why's". |

Yeah, exactly. And I accept that others know an infinate amount more about this than I do. And they've weighed in. Decision final. Next. Onwards and upwards. But "my wheels" are still turning....  I guess I should self-educate with the "minting process", because, frankly, I don't see how this could have been done PMD OR at the Mint !  |

I recommend one book in particular that has been a big help to me in learning the minting process- Official Price Guide to Mint Errors by Alan Herbert. The title is a bit of a misnomer, the main emphasis is not on prices and the ones given are decidedly on the generic side. Herbert breaks down die varieties and mint errors into the PDS system identification system- Planchet, Die, Strike. Everything caused by the Mint will occur during one of those stages. The book gives written descriptions as well as photos for some of the errors and there are various charts listing things like planchet tolerances, die life cycles, etc.

I agree. That book helped me tremendously, and although they do list "rough" price ranges, I rely more on the rarity scale listed for each error.

PMD - Post Mint Damage. Anything that happens to damage a coin after it has left the minting press - to INCLUDE damage to the coin at the mint or in the wrapping machines. This term is used pretty openly to describe anything odd that's NOT a mint error.
