Before Memory Lane Inc. sold the lone PSA 10 1948 Bowman Yogi Berra RC for $192k in 2017, Mastro moved the gem mint example in their April 2006 Sports Catalog Auction.
Mastro wrote, “This singular card is the ultimate complement to a high-grade assembly of its series, and it dominates the field in establishing the industry standard.”
Today, of just over 2200 graded samples, it’s still the only Gem Mint example.
As I said, Memory Lane Inc. sold the card for $192k in May 2017. You can see that it had been reholdered into a case I believe it remains in today.
