@RamenCatholic I worked in jewelry for ten years and I can't tell you how often I had someone bring in dental gold, sometimes with the tooth attached. Some people bring in nasty stuff, like watches that "need a battery" and when you pull the back off, the inside of the case smells like a bait shop.
Favorite was the couple that came in to get a gold band made, they weren't sure what the ring size, but they brought a knotted loop of string that was *way too big for a finger* for size reference.
