Appears uncirculated at first glance, virtually full luster and all details sharp. But close inspection shows a trace of rub on very highest points on the highest points (forehead, cheek, and eagle’s breast). Obverse:  Traces of wear show on hair above eye, ear, edges of cotton leaves and high upper fold of cap. Luster is gone from cheek.
Reverse: There are traces of wear on breast, tops of legs and talons.
