@baseball_cards Well, in reality most were NOT thinking money, most of us fans wanted to complete our set and take the doubles out to the park to chase Sigs. Kept a wrapper for the front page of the set.

How one collector turned $50,000 into $12.6 million

Anthony Giordano took a $50,000 gamble by purchasing a 1952 Mickey Mantle from "Mr Mint", Alan Rosen, who purchased 5,500 1952 Topps cards, including dozens of Mantles, for $125,000 in 1986.

For many decades, nobody knew Anthony owned the 52 Mantle, but his sons decided he should get the card graded and that it was time to finally part ways with it.

In August 2022, Anthony's 52 Mantle sold for $12.6 million, making it the most expensive sports card ever sold, until the Kobe Jordan Dual Logoman, which sold for $12.9 million

Counterintuitively, this isn't even Mantle's rookie card (that distinction belongs to his 1951 Bowman), but it's the more iconic of the two and the centerpiece of what many consider the most important set ever printed: 1952 Topps, the set that introduced color photography, team logos, and stats on the back to mainstream card design.

Per hobby legend, Topps once loaded pallets of unsold 1952 cards onto a barge and dumped them into the Atlantic to free up warehouse space.

Three decades later, that scarcity is why Anthony's SGC 9.5 example — described by Heritage as the "finest known example" — sold for $12.6 million.

[Darren Rovell @darrenrovell]

This is now the most intriguing auction of 2026. What will be the grade of Topps’ 1952 Mickey Mantle in the redemption?

A PSA 8 is $1.5M.
A PSA 7 is $550,000.
A PSA 6 is $275,000.
A PSA 5 is 200,000.
A PSA 4 is $150,000.
A PSA 3 is $125,000.
A PSA 2 is $90,000.

Think market will predict it’s a 5.

OTD in 1903 in Starkville, MS, the great James Thomas “Cool Papa” Bell was born. His nickname ranks as one of the greatest of all-time and his speed and base running ability was the stuff of legends, but it was very real!
