Ken Griffey Jr Autographed Memorabilia

Ken Griffey Jr is one of the most beloved players in baseball history. "The Kid" combined a sweet left-handed swing, jaw-dropping athleticism, and effortless charisma into a career that spanned 22 major league seasons with the Seattle Mariners, Cincinnati Reds, and Chicago White Sox. With 630 career home runs, 13 All-Star selections, 10 consecutive Gold Glove Awards, and the 1997 AL MVP, Griffey dominated the 1990s and became the face of an entire generation of baseball fans.

His 2016 induction into the Baseball Hall of Fame with 99.3% of the vote -- the highest percentage in history at the time -- confirmed what collectors and fans had known for decades: Junior is an all-time great.
