Furthermore this in effect is what TPG does aswell. Grading whether its by Spink, baldwins or even ourselves is our opinion, perhaps the buyer felt it was conservatively graded in auction ??? I remember years ago I had a gothic crown which was listed in auction as almost uncirculated. I sold it accordingly, only to find out at a later date its buyer had it graded and it achieved a 67 grade at PCGS. It went from being a 5,000 coin to a 30,000 + coin over night
