Vtg Ferdinand Austrian 1531 Thaler Eagle Button Crest Gold Tone Shank Brass 1"

Vtg Ferdinand Austrian 1531 Thaler Eagle Button Crest Gold Tone Shank Brass 1" * Measures approx 1" diameter. * I believe this is a depiction the obverse of a 1531 Austrian Thaler coin. It is not an actual coin. * Back and shank look like unpolished brass. I'm not sure what kind of metal the front is made of. * In good pre-owned condition. Please see pics.
