first some pictures of the reverse reflectivity.


Next I thought I was looking for a polishing mark on the left. Though I must admit I not certain where it is in the offical picture.
I looked at the VAMworld photos and copied the descriptions below
More confused now.

Obverse II 1 - Slanted die scratches in top of I and bottom of B in Liberty. Die chips at top and bottom inside of left 8 lower loop. (Also occurs VAM-1B)

And many thanks to all for input and even more light in the darkness of my ignorance. Ignorance is correctable, Stupidity is another matter.
