While it can be difficult to match vintage baseballs to a specific event, this game used baseball can be directly traced to Mickey Mantle's 53rd career home run. According to the enclosed notarized Letter of Provenance, this Official American League (Harridge) ball was in play on September 1, 1953, when the New York Yankees visited Comiskey Park to take on the Chicago White Sox. Mick homered in that game and "Aunt Emma got the ball." Ball shows use with some staining and "Mickey Mantle's 53rd" has been written in blue marker in unknown hand. In just his third Major League season, Mantle was coming into his own in '53 with 21 homers and his second straight All-Star nod, touching off a decade-long span of terrorizing American League pitching while earning three AL MVP honors over that period.
