This one was always my favourite when I was a kid, mostly because of its size. Always brought it to show-and-tell for the class. Since I'm investigating my coin collection, I might as well know where this thing came from, as I have no idea. I'm assuming it's some sort of cheap copper/brass medallion, but its still a cool piece. 4 Chinese symbols on the one side, with 3 animals and a person on the back. Diameter = 8.3cm thickness = 3.5mm
