Forget rookie cards ... here's a WAY cooler piece of baseball memorabilia -- Mickey Mantle's SIGNED Trump casino gambling cards!!!
That's right, the player's cards Mantle personally used to throw down bets at Donald Trump's casinos in Atlantic City -- the Trump Taj Mahal and Trump Plaza -- are hitting the Robert Edwards Auctions block.
So far, bidding has passed the $1,000 mark ... and we're told the two pieces of plastic could fetch $2,000 when all is said and done.
The cards are DOPE -- they both display the baseball legend's name and card numbers on the front .
