All 11 of these official baseballs are single signed and most are EX to NRMT with a few showing some toning. The three with base and nameplate are one-time home run king Hank Aaron, two-time AL MVP Frank Thomas and Cal Ripken, Jr., whose ball bears a logo commemorating his record-breaking consecutive game streak. The other balls feature the signatures of Willie Mays, Pete Rose (with hit total - 4256), Mickey Mantle, Duke Snider, Alex Rodriguez, Yogi Berra, Mike Piazza and Derek Jeter. The signatures average 7-8/10 and are all in ink.
