Yes, 6FS but borderline. Lot of dings on the steps but the lines between appear intact. The nickel shows obvious evidence of circulation and full step at this condition and date is common, easily found so no value beyond face. Keep in mind the full step award by TPGs is for Business Strikes only. All proofs will normally be expected to have 6FS by their very nature and therefore grading companies do not put it on the slab label. To be clear, this nickel does not warrant slabbing.
