1975 Mexico 20 centavos shows a roughly 20% horizontal misalignment of the hammer (obverse or eagle-bearing) die toward what would ordinarily be the 1:00 position.  The hammer die is also rotated about 150 degrees clockwise.  Since the rotation is so great, we are able to distinguish this from a pivoted die error.  A pivoted die error is unlikely to reorient the design more than 90 degrees away from its normal position.
