They include his 2004 World Series ring, valued at $50,000 to $100,000, his 2007 World Series ring, his 1986 and 1975 American League Championship rings, autographed baseballs, bats, cards, trophies, and the Rolex watch given to Pesky when his number — 6 — was retired by the team. In all, there are over 200 items. (A portion of the proceeds from the sale will be donated to the Jimmy Fund.) “We are very proud to share with fans a unique life, and a history of baseball stretching over seven decades,” said David Pesky, son of the player nicknamed The Needle. A teammate and close friend of Ted Williams, Bobby Doerr, and Dom DiMaggio, Pesky was with the Red Sox for 61 of his 73 years in baseball, as a player, coach, and manager. He died in 2012 at the age of 93.
