@dear, yes a great find. To me, it looks like there are three distinct regions on the reverse. In the upper left, the clad seems to have peeled off first, perhaps very soon after striking. Then in the middle, there is a region of missing clad that seems to have been helped along a little, perhaps by an awl or other pouty metal object. I say that because of the scratches/gouges near to the eagle's beak. Then on the bottom right, is a section with some remnant cladding.
Any thoughts on this theoretical set of events?
