@Eduard- boy, you sure do have some lovely US type coins. Only the rim hits would make me say MS61. Otherwise the fields are awfully nice and clean for that grade. I'll be charitable and say MS62 ... PL. If it's not a subdued proof. I dunno.
Thank LordM! At this stage I am thinking circulated proof based on appearance, your guys comments, and that very informative website on Seated Dollars. Maybe I'll have the opportunity to consult an expert.
