I am rather disappointed at the lack off response to a legitimate question.
The photos were my attempt to use sunlight to give a perspective. Obviously, I failed in that attempt.
I have spent many hours referencing many resources without results.
The obverse rim, (in your hand), is cleary non semetrical with the reverse rim, as far as distance above the corresponding field area's.
Another observation. The cruddy edge following the rim on the obverse, is not crud. Many hours in acetone says so. As this is a 90% silver coin, I am not familiar with the reactions that would effect one side and not the other. If you notice, this condition barely exists on the reverse.
Much less, the more normal rim.
In layman's terms; "The front is mushed in deeper than the back, and it looks like the silver is fallin" offin' the front side rim edge". It sure don't look like something I look at everyday.
I can create more images if anyone is interested.
