The Yankee slugger has signed each of the seventy-two Official MLB (Selig) baseballs in this lot, with the same precision and grace he displays at the plate. Every blue ballpoint "Gary Sheffield #11" autograph grades as 9/10 or better, with most being Perfect. Equally impressive are the snow white and flawless surfaces on which they are written, as the balls themselves, each with their own "Sheff Authenticated" hologram, are mostly Mint as well.
