Class VIII : Tilted Hub Doubling

Tilted hub doubling occurs when there is a misalignment of the die axis resulting in the die faces not being parallel. This can occur because of several reasons.

Class VIII is probably due to slippage of the die or the die not being level in the coinage press.


What to look for :

Parts of the coin could be impressed with greater depth of design than the other. Doubling can be on the top of the letters but not on the bottom or on the bottom of the letters and not on the top

It is very difficult to show this in a photograph because there is no depth of field in a photograph.
