Seattle Mariners Autographed Memorabilia & Signed Collectibles

From the electric swing of Ken Griffey Jr. to the surgical precision of Ichiro Suzuki's bat, the Seattle Mariners have produced some of the most iconic moments in baseball history. Founded in 1977 and calling T-Mobile Park home since 1999, the Mariners hold the American League record with 116 wins in a single season (2001) and have built a loyal fanbase across the Pacific Northwest. Now you can own a guaranteed authentic piece of that legacy with Pristine Marketplace's curated collection of Seattle Mariners memorabilia.

Our Mariners inventory spans over 3,400 authenticated items, from autographed trading cards and signed baseballs to game-style jerseys, framed photos, signed bats, and mini helmets. Whether you're hunting for a Ken Griffey Jr. rookie card, an Ichiro-signed baseball, or a Felix Hernandez perfect game photograph, you'll find it here.

Legendary Mariners Players

The Mariners franchise has been home to generational talent. Ken Griffey Jr. — "The Kid" — captivated fans with his effortless swing and highlight-reel catches, winning the Home Run Derby three times and earning 13 All-Star selections. Ichiro Suzuki shattered the single-season hit record with 262 hits in 2004 and collected 10 consecutive Gold Glove Awards, becoming one of the most beloved players to ever wear a Mariners uniform. Edgar Martinez, the designated hitter whose name now graces the annual DH award, delivered "The Double" in the 1995 ALDS — the hit that saved baseball in Seattle. Randy Johnson, the 6'10" Big Unit, dominated hitters with a devastating slider before going on to collect five Cy Young Awards. Felix Hernandez threw a perfect game in 2012 and anchored the rotation for over a decade as King Felix. Today, Julio Rodriguez carries the torch as the franchise's newest superstar.
