Graded by PSA EX-MT 6. Similar to other pin issues of the day, The Diamond Gum pins feature a picture of a player on the front with his name, with the back containing a paper advertisement for DiamondGum, reading: “Get a Collection of Ball Player’s Buttons Free with Diamond Gum.” Superb overall condition with no noticeable edge chipping, with a near flawless paper ad. One of the rarest Mathewson period issues in the hobby.
