Greaser and a very nice example of one.

Probably a Greaser, but if the reverse is similar it could be an Inadequate Upset Error. |

Here is the reverse. I can see some on the UNUM - but very fat devices - figured it was from a Die Deterioration. Something new for me "Inadequate Upset Error"? What is that about?  |

They put the planchets in a machine that compresses them making the outer edges thicker. When it is inadequate, the edge is not thick enough to receive a strong strike in several areas on both sides. I think your coin was Struck Through Grease because the reverse looks normal. |

Struck through grease. Too bad for the roller machine damage.

The best way to tell it is was Struck Through Grease is to check the un-affected devices near by. Normal devices are tapered so they are narrow at the top. When grease gets into the die, the devices will look a bit wider. (depending on how much grease is in the die) Note the weak devices on your coin next to the normal ones. See how they are wider? That is how you tell if it were an grease issue. If they were damaged, the devices would be normal sized and distorted on the tops of the devices. They also be flattened with circulation and rounded and enlarged. (especially on silver and copper coins) |

Thank you for the great explanations all - I didn't quite know what to look for to tell the difference between the 2 situations - what CM wrote about I now know that is the "Weak Strike" ones that are mentioned here on the forum so if I come across one that the rim is weak (harder to tell on the quarters because most of them don't have much of a rim to start with) and devices are faint then it could be that problem as long as the devices are normal in size.

On a weak strike the rims and higher devices are what to look for. But consider, why is it a weak strike. Most often it is because the planchet is thinner.    Other times it is the machine fault.  Hard to tell the two apart unless you weight them. |
