Weakly struck Fine with patchy toning, technically full pillars-and-waves and cross-lions-castles, two dates, also three bold mintmarks and two full assayers, the ones flanking the cross showing clearly the egregious error (basically the correct orientation if the cross were inverted), first example we have seen. Pedigreed to the Robert Mastalir collection.
