If I could guess with a degree of confidence, I would. But we do need pics that don't make the coin look unnatural and that show surface preservation.
Beautiful coin but obvious wear on the obverse (hair) and reverse (upper feathers) plus lifeless surfaces = needless/inept dipping.
It appears to me to be an AU coin that has been polished. I have one that looks very similar, purchased in the "early days" before I learned to appreciate original surfaces.
