This appraiser feels PCGS's grade of this rare coin is fair. Taking a look at coins at nearby grades on https://www.pcgs.com/coinfacts/coin/1879-s-1-vam-9-reverse-1878/images/133858 shows just how tight grading can be. This specific coin's very minute flaws can be seen on photographs particularly at the edge and among minor surface abrasions.
If the coin were resubmitted, attaining a *PCGS* grade of 65 would indeed likely make a significant difference at auction. At a 64+, a FMV of this piece is approximately $3,000 to $4,000 based on recent auction sales. A 65 would likely double that pre-auction estimate.
