“Ghost Adventures” star Zak Bagans ain’t just chasing ghouls — the dude’s a major sports buff, and has been dropping serious cash on some top-notch sports memorabilia.

The paranormal investigator tells TMZ he splashed a jaw-dropping $160,000 at Goldin Auctions to snag the NBA Rookie of the Year Paolo Banchero Best 1/1 rookie card, which is most definitely a sports collector’s dream.

Also, the card is signed by Banchero himself in sleek blue ink — which undoubtedly increased its monetary value.

Zak’s not just splurging for kicks, he’s playing the long game here … saying the card could be a goldmine down the road and worth millions if he wins an MVP or future championship. Talk about a savvy investment move!

What’s more, the person who first scored that epic NBA rookie card before it hit the auction block was none other than Jonny Venters, the Atlanta Braves All-Star pitcher!

Venters spoke to the owner of Goldin Auction, Ken Goldin himself, about getting his hands on the holy grail of sports memorabilia — with KG dubbing it the ultimate hit from 2022.

But, back to Zak, he’s clearly making waves in the sports collecting world — so much so that he tells us he’s developing a whole TV series around it. Safe to say, if his ghost-hunting gig hits a snag, he’s got a solid backup plan right in the heart of the action!
