Yeah. I think it's better than 65, too. These delicate PL surfaces are prone to marks and the only distractions on this one are the die polish lines which were there from the onset. In addition, it's a awesome strike. I think it could easily command higher in the market.
It definitely punches the 65 grade. and no doubt PL. I looked up a few that had more breaks in the frost on Robert. One was a 66 PL I am satisfied with the grade as there is very slight contact in the field infront of his forehead and nose. Some of the mirrors are gone at the rim around Gen and Lee obv. The hardest part of this grade was that we don't see the coin enough to judge how a TPG will grade them.
I am by no means an expert on these but yours appears to be a different finish. Like PF versus MS. Mine has more of a matte appearance. The mintage on these wasn't very large so I can see him taking the time to make 2 sets of dies. I purchased mine as part of a graded set of these that Heritage sold several years ago.
When I was searching grades I saw a few, like yours looks like I need to finish the set and get the other die pair.
