the 84(P) is normally sharp and bold. the reverse looks ok but the obverse strike AVG- the obverse looks like its missing most of its luster. the eye appeal is AVG- also. I think its AU so AU58 weak strike.
maybe improperly handled or stored. obverse may have had a light clean which removed the luster a while ago and then was not rinsed properly leaving this toning to develop and the lack of luster. hard to say
For what it's worth, not a pro, but I have looked at loads of Morgan's for comparison, and I thing the TPG's are more lenient on Morgan's, in part due to age. Having said that....I think this will get a MS-62.
