PART VI. Striking Errors:

Die Alignment Errors:

Compound Misalignment:

Horizontal / Vertical

Definition: Any two of the four types of misalignments — horizontal, vertical, pivoted, and rotated — can occur in combination.  Illustrated here is a dime that features a 50% horizontal misalignment and a vertical misalignment of perhaps 15 degrees.  The strike is also exceptionally weak.  Coin courtesy of Paul Heinen.
