The reasons I'm leaning towards bad is the 80 percent silver, the weight with wear being heavier and you can see what appears to be a seam or unfinished edge around the octagonal sides. The thickness various depending on where along the edge of each section measured. Starting at 12 and going clockwise I get 2.43mm, 2.39mm, 2.34mm, 2.43mm, 2.75mm, 2.47mm, 2.31mm and 2.52mm. The widths are 12-6 position 30.69mm, 3-9 position 29.93mm and 2-4 position 31.06mm. These measurements are all approximate. If the 80 percent silver is correct, there's no way this is good.
