Looks just like PMD -(post mint damage) from circulation |

Yes it did. It's a rim burr.

This does not look like a rim burr to me, since it is incuse rather than looking like a flange of "extra" metal. I have seen this exact kind of rim damage on 25c straight out of plastic wrapped mint rolls. I'm not sure what caused the damage, but it may have occurred after the coin was struck but before the coin left the mint. Once the coin is taken out of the roll it's impossible to prove it's not simply PMD. |

It got whacked or pinched in one of the feeders after it was struck .. PMD. |

I'm not too sure it's PMD, there appears to be a Blakesley effect opposite the gouge. "Dipping" is not considered cleaning...

Thanks for all your responses. I'm learning a lot...I googled the Blakesly effect and found this link: http://board.conecaonline.org/showt...anchet-ErrorLikely old news for most of you but for me it filled in a lot of the gaps about what you guys have been talking about in this thread... |
