Mickey Mantle Upper Deck BaseballsI don't believe the information on how many baseballs he signed for Upper Deck is available but, a Mickey Mantle single signed baseball typically sells for about $400-$600. Mickey Mantle was under contract with the Upper-Deck company before he passed away, and baseballs that have the Upper-Deck hologram could sell in the $1,000-$1,500 price range.
