In Major League Baseball, there are semi-stars, stars, and then there are superstars. This impressive lot features four single-signed baseballs, each autographed by a true Baseball Hall of Fame legend whose career helped define an era. Included are Sandy Koufax (Dodgers)—signed on an Official Major League Baseball (OML), Hank Aaron (Braves/Brewers)—signed on an Official American League (MacPhail) Baseball, Whitey Ford (Yankees)—signed on an OML Baseball, and Yogi Berra (Yankees)—signed on an OML Baseball. Each ball has been authenticated by PSA/DNA, ensuring the signature’s legitimacy and long-term value.
