The 1920 Saint pictured above is NOT an MS66. As far as I know the highest graded 1920 Saint by PCGS is a single MS65 coin- a former Eliasberg collection piece. Their are five or six NGC MS65's floating around (I think the NGC stated pop is 10 or so).
Unless you are purchasing for melt - or slightly above melt, I would stay far, far away from NTC, WCG, or any other basement slabber.
