Two queries: 1. Is this attribution correct? 2. Is it right? (Ie not a fake or a later reproduction?) It appears to be mostly Bronze or other cuprous alloy, and there is a little verdigris but also red corrosion at one point on the edge. It has a pale gold surface as shown - as plating was obviously impossible at that time, it would need to have been dipped in molten metal. I have little experience of these and the books are pretty brief on the appearance of the Bronze staters - is this all likely/possible?
