Pennsylvania (South Philadelphia, to be exact) phenom Mo'ne Davis has been a big enough star in the 2014 Little League World Series to land on the cover of Sports Illustrated. Now, her autograph is fetching more than $500 online.

That's right, the 13-year-old's autograph is worth quite a bit of money.
A Davis-signed baseball was put on eBay last week at a starting price of $9.99. The bids have skyrocketed all the way past $500 as of 3:30 p.m. ET on Aug. 20.
Bids will be accepted through Wednesday night, so the bidding may go even higher.
