Have you tried a tooth pick on this area. I've seen a clear grease film in that area. If it is, then it moves quickly.

Thanks coop - no movement under a toothpick. I am fairly certain is is the same material as the coin. (I had not thought to try that, though).

I do notice that this feature carries further around the rim, but less pronounced. It seems like it is extra metal which seeped out from under the rim - - is that possible?  |

What happens when a split planchet gets slammed into the collar by the strike? Could the edges "petal" outwards and get folded onto the faces? The other thought is a thin strip that got caught between planchet and collar.

SsuperDdave - is there a name for the first possibility you suggest? It seems to me that the second possibility is less likely because it shows up on both sides of the coin and in 2 different places on the reverse.

It might be split plating? If it keeps getting worse that maybe the cause.

Thanks coop - I looked up split plating here: http://www.error-ref.com/?s=split+platingI am really not seeing any resemblance at all - not even for split/peeling plating... I have been reading through a bit of error-ref and cannot find anything at all even remotely similar to this coin. Any suggestions for next step to identify this? Thanks! |

I am wondering if this could be early stage die attrition? This would be before the beveling forms. Please look at the last photo on the following link. It is the only thing I have found which has similar features. Note the area around the top of the letters. http://www.error-ref.com/die-attrition-error/Edited by Pete2226

It just looks like PMD to me. |

I have an LMC from the 80's I've had aside and been meaning to post it has this same exact feature but only a small portion of the rim on the obverse not close to the amount you have pete but exact same look-I will try to find and post a seperate thread-I did the same pete,looked up split plating and didn't think it matched either-I really don't see this as PMD tho? |

How could it be PMD? What would be the mechanism? What would produce this raised area? Slamnbass - let me know when you post. |

it looks to me too like it had to be done at the mint. it is behind letters in "trust".

Minor rolling fold? I see it quite often, so I always throw them back, but have wondered exactly what the cause is.

At this point, bunches of magnification are required. What does it look like where edge meets field and rim? Is it possible with magnification to see where a slip of metal might have been struck into the rim, where it starts and ends?
