jimbean802, a die chip is not a mint error. It's considered a "die event" - relatively common and generally without a numismatic premium.
Please explain the "thin air" in the title.

I wonder if "thin air" = "mint error".

@ Spence: IMHO the OP reffere to the expression "vanish in thin air". I translate the "My thin air" with: " do my expectation for this coin will disippear in thin air?"
This it is my guss.

Hondo Boggus, "die event" is not a recognized term and it conveys no useful information. A die chip is a mint error, specifically a "die error". It's a trivial error, of course.

So, the die failing from normal use is a die error? I believe die event is a valid term identifying a normal life span of an otherwise normal die being worn out/down. John1  |

I do not understand anymore. If die chip it is Mint error, so I can understand that a Die crack it is Mint error or the Cuds? and do not fall in the category of the Die Deterioration? All those happened in the life span of a Die and if so an Die Deterioration Doubling or Orange peel or Die Deterioration lines must go in the same category of Die Error. I wrote this because the precursor of an Chip or Cud are Die Cracks. I do not knows. So for me seem we have two different Die errors: Die surphace error and Die structural error which occurs only in the span life of the Die. I remember that an Mint Error will be only when the Human activity it is involved, but machines or any parts default in the course of production are normal events. Maybe Mike will explain better, but I am affraid that if an Die crack or Die chip it is Mint error we made face to a flood of very rare error or rare error on coins. Maybe the bord who decide the nomenclature will take the time to adjust the lexicon of errors, varieties and events. Silvio |

John1, any form of brittle failure is a die error, even if it is trivial in size. While it's more likely that die chips will form during later die states, this is by no means always the case. Obviously, the same thing goes for die cracks. It's only standard Die Deterioration that can be dismissed as a sign of normal aging. Error coin writer and researcher.

Thanks Mike for explanation. Using the word "brittle" you explain me well what it is. In the study of the Die manufacturing at the Mint allways it is calculate the brittleness of the material. This propriety was one important factor to switch from the double squeeze to single squeeze. As generic for all I will put here the material definition for brittleness without enter in the FCC and HFC: Quote:
In materials science, brittleness is the property that characterizes a material's inclination to fracture with minimal plastic deformation. Brittle materials have a poor capacity to absorb impact energy before fracturing. |
