Grading and value of the '89 UD Griffey
Looking to put together a HOF PSA set, I was looking up the '89 UD Griffey. This card has been graded at PSA 60,546 times! Am I correct to assume this is the most graded card of all time? Also, with 20000+ PSA 9 and 10 am i also safe to assume this card can only go backwards on value? I am not sure of the trend but I would assume the PSA graded cards will eventually clear 100,000. What is everyone opinion on the future and price action of this card?
