This is a monster of a set! The HOF designation can change the demand for any player’s autograph, especially the single signed baseball. The great hitters, the great pitchers and the great defensive players all reside here; it is the ultimate autographed baseball set. It is also a mountain of a challenge. In fact, several of the names on this list either have no known examples or so few known that the supply is miniscule. In addition, this is where all the great players who did not reach some of the exclusive clubs can be found like Lou Gehrig, Johnny Bench or Duke Snider.
