SPP would the sand paper not have left scratches all over ? and if you look very close you can see what looks like a bulls eye pattern , also would the rev wear not be the same on the entire surface....

Almost looks as if it was on a lathe machine! Its obviously PMD |

darryl, it does have a turned effect hence the bulls eye , but the weight is dead on what it should be so that would mean no metal has been removed , same with sanding , the weight would be off ..Unless I'm mistaking ... Could there have been an issue with the die ? or as john said maybe struck on a foreign coin

IMO it's PMD and can be easily made in a machine shop with a vertical hand press with the coin sandwiched between 2 smaller steel washers. |

Dryer coin. these things take on all kinds of different look, depending on the dryer make and exactly where it got stuck. PMD |

@ artdio...if you take a look at the "Bulleye" so to speak, you will notice that its really the only spot on the coin that has detail.
A Lathe job of some sort or as Broken-Coin or SPP suggest is probably what happened to this coin.
The small amount of detail which is sanded away, wouldnt effect the actual weight of the coin by much.

I have a coin with similar damage (not the bullseye though), it was id as a Dryer Coin as well. Similar wear pattern, maybe yours got rescued earlier. |

Ok so lets say its a Dryer Coin..Someone school me on how this happens? I have taken may apart and I have no idea where a coin would lodge itself and not get chewed up ? or damage the drum bearings |

Here is a pic of how mine looks, I am not quite sure where it would hide exactly, but I imagine it would sit somewhere between the drum and space around the door. I've seen coins stuck in their before and they seem to just rattle around. You'll notice that the 12 sided rim has been rounded on mine which makes me think yours didn't spend as much time. Assuming that is the underlying cause, either way it is kind of a neat coin.  |

600 grit sand is pretty fine stuff, in a tumbler it would not leave scratches, but a frosted surface... also depends what the sand is made of (e.g., quartz, garnet, titanite, etc...)
