You sure have "something" interesting!
What is it exactly that you're seeing on the reverse near the neck?
Tuberale, on the reverse, are you looking at the smaller image or the larger? The larger is out of focus, but the smaller shows much better detail. I don't see doubled letters on the smaller image. ...Then again, my vision still fluctuates wildly sometimes as well.
I see "something" to the left of the neck, but my extreme lack of knowledge in this area keeps me from knowing just what.
If it was struck partially outside the collar Frank it would show on both sides. It's a misaligned die.
