All
Morgan dollars are VAMs (die pairing by known obverse and reverse dies).
A specific rotation on a coin is not a
VAM in itself, all coins could concievably have rotation.
Morgan dollars are pretty hard to find with more than 5% rotation, and any more than that will bring a good premium generally. I've seen a few 15%-180% they usually bring at least $100.00+ over the value of the grade and date the more the rotation the higher the price asked is generally the rule.
