TPGs are all about luster in mint state. This coin's luster looks a touch soft. Like 63 or 64 soft. However, the coin's surfaces are nearly flawless -- 65+. Color looks off to my eye (too perfectly brown) -- enough for a TPG to question it perhaps. I'd guess 64 BN or a bodybag & I hope for the former.
oh my.. thad... wow.... 65+ details for sure. PCGS is stringent with 65BN so if there is no luster - which it doesn't look like it has. 64BN jeez I would love to see your collection some day. Ever thought about cataloging it? edit: sorry for the redundancy - I looked at the coin and hit reply without reading others comments. Everyone already nailed it. IMO of course!
