How does a die clash produce marks on the incuse part of the die. I can understand seeing it in the fields, but not on the relief.
Die Clash and Die Chips(IDB) near eye and mouth. Nice error coin. Die Clash in the design is called an Atypical Die Clash. It does not happen often but does happen. Here is a 1972 WQ with his chin and mouth on the eagles wing.
Great clashes! You should create an averlay of the Reverse over the Obverse to show folks how it looks and where they came from.
OK, but how does it happen? I would imagine that the dies would have to meet with such force to be able to get to the bottom of the incuse portion that the dies would be ruined. Both the chin and the wing are incuse on the dies so how can they reach other during the clashing of the dies?
The outline of George's chin is not incuse and it struck mid wing, the lowest relief section of the opposite die. Franklin's ear is a low relief area of the coins design. Add it up and there is less than a millimeter of difference between field and low relief.
It is not George, it is Roosevelt. And the clash mart is just below the ear so I still don't see how this can happen without ruining the dies. I am nit disputing your statement, I just can't get visualize that heavy a strike.
Depends on a few things. Severity of the clash, coin condition and what one person would pay for such a relatively common error.
