A rotated reverse die. I'm not sure how much rotated it is. Hope it's more than mint tolerance. Very cool!
You can't really tell which Die rotated. So it would just be called a Rotated Die Strike. It looks to be within tolerance.
If you line it up properly, I believe the rotation will be less than it shows on the reverse. Mint tolerance is 27 degrees, and I've found that any US coin has to be rotated at least 45 degrees to be collectable. (some Silver dollars might be collectable w/less rotation) 45 Degrees would mean that if properly aligned on the obverse (top of head pointing to 12;00), the top of the reverse would point to either 1:30, or 10:30 (if it's a counter-clockwise rotation) This warwick is within tolerance, from what I can figure.
....although the popular term "Rotated Reverse" is still used, and acceptable, because the Reverse die is rotated, VRS. the Obv. die - although we don't know which die actually rotated, the reverse die is rotated in RELATION to the Obv. side.
