Hope this is a better image. This measures 2.5 inches across, is non-magnetic, and maybe copper Also appears that the two upper stars have been painted red. The areas that shine, well they shine like a new penny. The only thing I did was wash it under H2o.
Can not see any markings on the back or the small rim. Do not know if this item was stamped, pressed or hammered, but the "pressed" areas on the back are smooth and not "speckled" like the rest.
