While it didn't quite reach the $3.12 million price tag, a mint-condition 1952 Mickey Mantle Topps rookie made a run at the record for most expensive baseball card.
According to ESPN's Darren Rovell, the item recently sold for $2.88 million through Heritage Auctions. The only baseball card to ever fetch more was the legendary Honus Wagner card.
Former NFL offensive lineman Evan Mathis turned out to be the seller. Per ESPN, he did so to buy a "dream home" for his wife and three daughters. To acquire the card, he traded away "90 percent" of his previous collection and made payments.
