Ken Griffey Jr. Game-Worn Jersey Signed Mariners – COA Player Letter & JSA Full LOA

At first glance, this appears to be a batting practice jersey of future Hall of Famer Ken Griffey Jr., but photo evidence clearly reveals that this style jersey was worn by the team as an alternate during regular season games throughout 1997 and ’98. Griffey, Jr. had 56 home runs and 147 RBIs during his 1997 MVP season.

The traditionally hard two-color tackle twill identifiers (glittery silver metallic thread) have softened and puckered lightly. “GRIFFEY” is applied to a mesh nameplate atop the verso numerals, and a Mariners team patch adorns the left sleeve end. A Majestic label is sewn into the tail, as is a size “48” flag label. Majestic’s “0006” (XL included) flag tag is located on the inner side gusset. Griffey Jr. signed the verso in blue felt tip “8” (with some assimilation). For added top tier authentication, “The Kid” signed the letter of provenance on Unique Sports letterhead.
