Good Evening, I am curious if the capped bust half pictured is worth any sort of premium because of this die rotation? I was not able to actually give a specific degree of rotation, but my guess is about 30 deg. I places the lines under the coin to help see the rotation. Is this rotation error common in this coin type? If you are able to point me in the direction of any specific books or websites dealing with this type coin, I would appreciate that information as well. Thank you for your time.
