1914-D Barber Dime PCGS MS62...WOW!

Here is an interesting coin. It has the look, clean surfaces and intense luster of a 65, but there is some minor disturbance of the cheek...not friction or wear, but busy-ness. Minor. Still, I cannot for the life of me figure how they settled on 62. I've talked about my concept of the LCG many times (Lowest Conceivable Grade), and the LCG on this one is 63+.
