According to NJ.com, there are dozens of Mo’ne Davis autographed baseballs for sale on eBay right now and recent auctions for the player’s autograph have been lucrative. One of the auctions for a Mo’ne signed baseball has already sold for $510.

And while the price point for Davis’ signature may have cooled since her team lost on Wednesday night, there are still auctions for a Davis autographed baseball going for over $120.

Davis has become a sports sensation ever since she became the first female in Little League World Series history to record a win last week. It helps that the win was also a shutout.

Steve Keener, CEO of Little League Inc., is less than thrilled over how people are profiting off of Mo’ne’s signature:

“I think it’s ridiculous. That’s absurd,” said Steve Keener, CEO of Little League Inc., which hosts the World Series in Williamsport, Pa. “(But) I don’t know how you would ever control it.

“We supervise the teams while they’re here, but we’re not with them every minute. So if any player in the Little League World Series signs a baseball for somebody, we have no idea what they’re going to do with that baseball after they get it. In some respects, it shows you why a lot of Major League Baseball players are reluctant to sign autographs anymore.”

Meanwhile, Brandon Steiner (owner of sports memorabilia company Steiner Sports) estimates that Davis could make “up to $100,000” in a memorabilia deal but he would hesitate doing such a deal because it would jeopardize Mo’ne’s amateur status and NCAA eligibility later in life. As long as Mo’ne keeps doing her thing, investing in a 13 year-old’s signature may not be the worst investment.
