A "museum-quality" Roberto Clemente rookie card could hit seven figures at auction, according to TMZ Sports.
The 1955 Topps rookie has a PSA 9 "mint" grade and may exceed the record price ($1.1 million) for a Clemente card.
Jesse Craig, who works for PWCC Marketplace, explained what sets this card apart.
"There are just so few copies of this card in this quality in existence that they require the highest level of custodianship possible," he said.
Craig added the Clemente Topps rookie is in "upper echelon of quality for vintage trading cards."
Clemente was a 15-time All-Star, two-time World Series champion and the National League MVP in 1966.
