This Zoroastrian/Persian plate weighs just shy of 8 ounces. There are no makers marks on it that I could find. It appears to be from the 1960s/1970s. It is 7 and 5/8ths inches wide. It is made of a white/silverish metal (not silver Ag) with copper highlights and black paint. The top flying creature (faravahar) is what gives it away as a Zoroastrian piece. Also on it is Darius seated with an immortal at the rear of the procession.
