I believe if you review the published A.N.A technical standards, either Obverse or Reverse will easily dictate a G-4 grade. It wouldn't surprise me to see the coin having a G-6 grade, as I've seen the "Premier" TPG grade that type/date coin in a lesser state, at a higher grade. JMHO
I'd give it an AG-3. But others may differ. Since this is a guess the grade and I presume you mean the grade on the slab, then... AG-3.
