Errers and Varietys Bedrock of the Community United States 74481 Posts	Posted 02/09/2019 1:42 pm I bought this rare Die Formation error on ebay for 33.77 plus 3.74 for shipping. This is not a Struck Through error or a Dryer Coin. This error was caused by the die deteriorating prematurely. The actual cause of the reverse die deteriorating rather quickly is unknown. Here's the article to Coin World and to error-ref. https://www.coinworld.com/news/us-c...ers.all.html http://www.error-ref.com/detail-erasing-die-wear/ Here's the error coin. And here's what the normal Harper's Ferry reverse design is supposed to look like. Errers and Varietys. Report this Post to the Staff

jimbucks Pillar of the Community United States 4692 Posts	Posted 02/09/2019 2:08 pm It looks to me like someone applied acid to the reverse. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 74481 Posts	Posted 02/09/2019 2:10 pm Nope. That's not the case jimbucks. Read those links. They will have detailed information on this. Although, it looks like Post Strike Damage, it's not. Errers and Varietys. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 74481 Posts	Posted 02/09/2019 2:18 pm Yeah Jim! It sure is! This is actually a rare case of Die Deterioration. It happened quickly and prematurely. Some process wasn't done correctly. It will make a good conversation piece! Errers and Varietys. Report this Post to the Staff
Panther Pillar of the Community United States 751 Posts	Posted 02/09/2019 2:34 pm I understand the concept of Die Deterioration, but how do they explain the apparent decrease in diameter of the die. The outside edge of the die appears to be reduced into the outside lettering ? If the die had it's edge reduced it would seem you would see a radical radius at that point ?

Errers and Varietys Bedrock of the Community United States 74481 Posts	Posted 02/09/2019 2:38 pm Not sure how to explain it Panther, since it's kinda complicated. It's a very weird coin. It's a very interesting coin for sure. To shed some light on it, here's what Mike Diamond said about it's possible causes. From Coin World article: Quote: "A number of questions spring to mind when contemplating this specimen. (1) Is this a normal pattern of Die Deterioration simply taken to its logical extreme? The smooth surface texture of the distorted raised elements and the merging of design details suggests not. (2) Did the reverse die deteriorate slowly or quickly? The other Harpers Ferry error I spotted on ebay shows a slightly less distorted reverse design, indicating that the distortion was progressive. Still, the absence of other examples may indicate that the problem developed relatively quickly. (3) Was the obverse die changed out, with the distorted reverse die inexplicably left in service? Or were both dies installed at the same time, with only the reverse die deteriorating? At this point, I have no way to tell. If this proves not to be a conventional case of Die Deterioration taken to its maximum limit, then it should be classified as a die deformation error. Perhaps "detail-erasing die wear" would be a suitable moniker. Poor quality steel, the wrong grade of steel, or improper die preparation (annealing, tempering, quenching) could be responsible for the distortion." Errers and Varietys.

Halo1st Pillar of the Community United States 2775 Posts	Posted 02/09/2019 7:18 pm Nice example E&V. I think the later part of the last paragraph from the Coin World article sums it up. I'm thinking this die missed the boat, somewhere in the die preparation process. Thanks, Doug.

Errers and Varietys Bedrock of the Community United States 74481 Posts	Posted 02/09/2019 7:49 pm You're very welcome Panther and thank you Halo1st for your feedback! I agree that this error most likely happened during the die preparation process, as it's not normal die wear. I compared it with my 1982 P LMC with severe Die Deterioration taken to its logical extreme and the die wear pattern wasn't the same. This die must have deteriorated pretty quickly and probably most likely only affected a single run, since there's not many confirmed examples. Errers and Varietys. Report this Post to the Staff
