 I was just wondering, how dose someone know how an error is created and what kind of proof do they have to show for it? Is it a coin or could it be a visual thing, as if they seen it as it is being created. Another, question could there be a coin out there that show proof of what are or somehow explained on what it really is?(speaking of errors)

First and foremost you have to be able to spot common errors and know their correct names. Also, you have to be able to distinguish between Mint Errors and PMD (Post Mint Damage) to a degree. If you are unsure it's best to get opinions in forums such as this by posting details about the coin, possible error and pictures. Some of the experts here can supply some nice links for you to learn from. I don't know any off the top of my head. Thanks. Jeff |

You could spend days looking at this location BJ posted. One thing that can happen on damaged coins is that if it was damaged with a nail/punch, the opposite side will show that damage.  Note the punched inward marks on the obverse and the reverse shows dent pushing outward. A sure sign the coin was altered. So if the coin is not altered ( PSD) then it should most the time be flat. (altered coins are often out of round/bent/twisted) There are some cases where the event happened during the strike, but know what to look for will help with your determination. If you question a coin post it here to be sure that you are not returning a coin that maybe an error back into circulation. A lot of common events happen to coins. Die wear/cracks/chips/die gouges/clashes/breaks/rim Cuds and other common events usually don't peak the interest of collector, but extreme examples do receive attention. But to me, an error is often just a one time event. |

Proof? As in a high-speed camera recording the production of every coin? No...
What there is, is a detailed knowledge of the minting process (as it has evolved over the years), which allows the expert to exclude things that simply cannot occur within the mint.

This, in a nutshell. The key to understanding errors is understanding precisely what happens during a normal strike. That understanding makes errors far more simple, and would cut traffic in this forum by 2/3ds. |

Now how about if you get 3 errors on the same coin now would that peak interest?
