"Tom Terrific" achieved his 300th win on August 4, 1985, while playing for the Chicago White Sox. This milestone solidified his place in baseball lore, as only a select few pitchers have reached the 300-win mark throughout the history of the game. To commemorate Tom Seaver's 300th win, this Official American League (Brown) game used baseball has been signed and inscribed "#300 8.4.85" by Tom Seaver in blue ink. Full LOA from PSA (for the signature only).
