66+*? Really? That's it -- I'm done. There is absolutely no logic behind TPG grading of these. I just bought a similar coin off eBay for $40, minus the toning. (diff. date) I *guarantee* it wouldn't grade any higher than a 64.
Looks like they gave that coin a 2 point bump for the toning. I wonder what the sale price would have been if the coin were only graded MS64*, which is what it deserves.
