Misaligned Die Strike on the Obverse. Centered Strike on the Reverse. Most of the time one side is centered. The blank planchet would be held by the retaining collar and usually the hammer die will create the misalignment. Off Center would show on both sides with some of the lettering and numerals missing because it was struck out of the third collar (retaining collar) that holds the blank planchet.
What? Third collar. (Retraining collar) this makes no sense to me. I think maybe You mean (Retaining Collar). Are you catching a train again?
