This old miniature copper Turk's head swirl mold is for candy or chocolate. It measures 2-1/8" diameter by just over a half inch deep. The lining appears to be tin and I'm not sure if it's food safe. I have owned it for more than 30 years but only used it for display. Unpolished, it's in good vintage condition.
