I've had this...thing...for awhile now. I have no idea what it is, I've been using it as a doorstop. It's metal, very heavy, and non-magnetic. It looks like copper, but I don't know if it's all one metal or a combination of several. It measures 9 1/2 inches from point-to-point, and 1 inch thick/tall/wide. Any ideas on what it is?
