These Ty Cobb pins are scarce and highly valued, representing 2 major names in the pin collecting game. One pin is from the extremely rare 1911 Diamond Gum set of 28, of which the Cobb, with his hat off, is the key. "Free with Diamond Gum" appears on the outer edge along with "Ty Cobb, Detroit. AM". The other pins, from the 1910-11 P2 sets, show a more traditional Cobb w/cap ringed by "Detroit Tigers" and "Cobb" on the large letter version, "Ty Cobb" on the small letter variation. All pins .75" in diameter and MT.
