I have a 1983 Olympic coin with an edge error. Pictured below  Can anyone give me information on this error? |

To my eyes, it appears to be a cut into the coin's edge that was made after it left the Mint. If such is the case, it is generally referred to as Post-Mint Damage ( PMD) and is not considered a Mint error. Collecting history one coin or medal at a time! (c) commems. All rights reserved.

 to the CCF I agree, this could not have happened during the minting process so no matter how it happened, it is considered damage. Someone has ruined a nice silver dollar. |

@guit, first welcome to CCF. Second, I agree that this coin didn't leave the mint with this edge groove. My mind went to the type of magician's trick called a "folding coin". Here is a previous thread with an example of this: http://goccf.com/t/352249"If you climb a good tree, you get a push."

Coinfrog's suggestion is a good one.
It may? have a slightly offset security edge.

Thanks everyone for the information. I ordered this coin in 1983 directly from the mint, did not buy it from a third party. When it arrived I opened the case and it fell out into my hand. The plastic was open and I could not get the coin to fit back in it. So it got a little tarnished. I'm embarrassed about that. Pictures below show the front and another picture of the edge in a different area. Will get a picture of the back and post it tomorrow. Thanks again - Mike G   |

to the CCF. I do not know of any mint process that would cause the effect you are showing. I'm looking forward to hearing if any experts can explain this as anything other than post mint damage. |

Hi Again and thanks for your comments. As I look at the first photo I sent I believe it is showing something that is not there; a groove around the edge of the coin. It is actually a difference of height of the left side of the edge and the right side of the edge. The difference is about .023" between the right and left sides. I am attaching a picture of the back and a new picture of the edge that shows the elevation difference. Thanks again - Mike G   |

I don't think I have seen this before but unless it can be explained how this could
happen during the striking of the coin, the only alternative is damage of some sort.

I very obviously guessed wrongly about the security edge explanation.  I am now going to have another guess: Step milled edge caused by faulty collar mechanism. |

Thanks again everyone. I am going to look into the "Step milled edge caused by faulty collar mechanism" idea. So, one last question: If this was one of your coins and you were absolutely positive that you got it directly from the mint in the condition pictured above; where would you go to find out exactly what you have? Is there someone I could contact and/or send the coin to for an opinion? - Mike G

I am going to Disagree. It appears to be damage done during the Minting process, JMO. A photo shows the Reeds are separated , in areas and the Reeds shown, do NOT Align properly, they are visibly off-Set. I am NOT sure again, Here there are Many experienced Numismatists, some specialize in Errors, M. Diamond, I believe He authenticates Mint Errors. If He comes along, I have not been involved with Him for Years...... Best Wishes

Interesting topic for sure. How could a coin be damaged in this manner at the US Mint?  I would reach out to Mike Diamond. He is a former president of the error coin association and a true world class expert on coin errors versus post mint damage. Mike contributes here at the CCF on occasion, but he is not known to hang out in this particular sub-forum. Perhaps the OP can ask for the mod dudes to move this thread to the US errors forum and retitle the topic to reflect the error in question. That might get Mike's attention. If Mike Diamond sees this coin and offers his views - then we will have an answer that we can all believe in. |
