A fold-over coin is one of
the most dramatic types of errors. It occurs when the blank is standing
vertically between the dies. During the strike, the force is so great that
it bends and folds the blank. These fold-overs can be on center or off
center, and come in many different shapes. There are a few fold-overs with
multiple errors, either with an additional strike or fold-over.
Denominations above quarters are very scarce.
