My all time favorite ball....and I'm a Yankee fan.
My grandmother passed away in 1988 when I was 11, and I was just starting to get into baseball cards and autographs (like every other kid that age). My grandmother had cooked for a neighbor, and when she passed away he gave me two autographed baseballs as a thank you for all he had done for her. This Ted Williams signed baseball, and a 1978 San Diego Padres baseball (sort of random, but that ball is loaded with HOFers; Winfield, Ozzie, Gaylord, Fingers, Billy Herman).
