Dinerman said:found something strange in a 10 dollar thriftshop special jacket (newer civilian bomber jacket- I like it- and it's just so beat up and funky. It's got the look - you know?)
anyway- it's a nickel- but someone's soldered a convex piece of nickel coated brass onto one side. It's worn through the nickel in parts, exposing the brass (or whatever metal it is) underneath.
you can click it and it sounds sort of like a cricket.
but I have no idea what it is or why it was in my jacket.
