I saw this today, it seems it has had a rough past. Right now it is at $31 with shipping. I don't know how it could have been damaged like this. https://www.ebay.com/itm/187233753059?
Careless owners is how it was damaged. An untold number of scenarios could be told about the life of this ASE.
Probably some sort of a crude bezel. Why would anyone buy it? The nice ones are “dirt common.” Many years ago I spotted a silver quarter that had been hammered into a square in a junk box of coins for well under going rate for “junk silver.” A savvy junk box collector I knew, told me to stay away from it. The market price scrap, well below melt.
