Rotated die coins usually occur in two different ways, the first being the mint employee installs the die incorrectly so the obverse and reverse do not line up properly when the coin is struck and the second is when the die becomes loose and then moves a little bit as each new coin is struck. Rare coins and modern coins known to exist with major die rotation (rotated reverse)of 90 degrees to 180 degrees.
