On Thursday night, Los Angeles Dodgers superstar Shohei Ohtani made history. Facing off against the Miami Marlins, Ohtani became the first player in MLB history to record 50 home runs and 50 stolen bases in a single season. The historic feat was accomplished on a monster home run to left-center field at loanDepot Park.

While history was made, Ohtani, the Dodgers, and MLB were unable to secure the baseball from the fan who caught it. Instead, said fan left the stadium with the home run ball in their possession. With that, it would undoubtedly be put up for auction. So, how much would a 50-50 club home run baseball be worth?

SCP Auctions’ Dillon Kohler told NBC Local that he wouldn’t be surprised to see Ohtani’s home run baseball go for $500,000 at auction.

“Just an incredible piece of history,” Kohler told NBC Local. “I wouldn’t be surprised if it’s $300,000-plus, maybe even over half a million dollars.”
