Mike - how would you distinguish a coin that was struck through a blank planchet from a coin that had a circular chunk of metal somehow missing from the blank?

If it was a defective planchet with an elliptical void in the obverse face, then the reverse face would be weakly struck.

If it had been struck through a partial uniface die cap, I would have expected a stronger ghost image of the obverse design to have bled through. Well, looking at it I seem to see the date and mintmark faintly showing. I've never seen any obv detail showing in the areas were a planchet has obviously been struck through before. |

I don't believe an obverse strike through would affect the devices on the reverse, as there isn't metal missing from planchet when it is struck.

Now that Conder101 has drawn my attention to it, I now see what may be a faint indication of a date and mintmark. That would ordinarily indicate we're dealing with an intrusive object thinner than a planchet. Perhaps it WAS a partial, uniface die cap. Hard to say.

I'm familiar with a die cap, but what is a partial uniface die cap?

You aren't striking through the whole die cap, meaning the cap is still on the die. The cap has fallen off the die and you are only striking through part of it.
Uniface die cap means that it is a late stage cap where the design on the bottom face of the cap is no longer visible.

So this kind of strike would only occur once, at the point where the die cap falls off the die?

A partial die cap is an off-center coin that sticks to the die and then is struck into at least one other planchet. If the original off-center strike is uniface, then you've got a partial uniface die cap as soon as it strikes another planchet.

While I have nothing to possibly add...this is a very interesting post to read--and learn.  |

So then for that coin to be stuck to the die and create a partial die cap, it would have to have been struck off center and out of collar, right? I'm assuming there's no other way for it to stick to the die in that position unless it was struck that way.
