Rare John F. Kennedy single-signed baseball gifted to Rollie Hemsley, who was a coach for the Washington Senators from 1961-1962. Official American League (Cronin) ball dates to the 1960-69 era, inscribed "For Rolllie" and signed on a side panel in blue ballpoint ink. Ball shows use and is in Very Good condition; it was part of Hemsley's personal collection and was likely used and signed at a game with JFK in attendance; signature rates 6/10. Over the years, only a handful of JFK autographed balls have come to light, making this a rare and valuable commodity. Comes with PSA LOA.
