On the seventh day of collecting, our historians found for you… a Mickey Mantle game-worn jersey! Mantle’s 1963 season was rife with injuries, but the all-star still managed to send the ball out of the park with an extra-inning, game-winni...ng home run on May 22. Mantle wore this number SEVEN jersey during that famous win in Yankee Stadium. The NY logo and #7 appear on the left breast and reverse in vintage stitch patterns. The jersey recently sold for $300,000.
