Forget Bryce Harper and Mike Trout ... one of the most valuable autographs you can get on a baseball right now is Donald Trump.
We spoke with multiple sports memorabilia experts who tell us the value of a Trump signed baseball used to be around $100 ($200 tops) ... now, it's worth around $1,000 depending on the quality of the signature.
"There's a big market for presidential collectibles," Steiner tells us.
So, where does Trump's autograph rank among other presidents?
