Curious, how would a double strike show doubling on the front and the back of the queens head? I was under the impression when a double strike happens it is only in one direction and all visible doubling will follow.
Usually when you see doubling on both sides of a design element it is
Machine Doubling due to the die vibration from side to side. But then again I have no idea when it comes to vicky cents, just an observation.
