About Our Baseball Mystery Boxes

The best way to describe an MLB mystery box is that they’re a treasure chest for any baseball aficionado. Each brims with unexpected gems in the form of autographed baseball memorabilia from some of the sport's most illustrious figures past and present. You’re always getting something worth at least as much as what you’re paying, and there’s a good chance it will be worth a lot more. Either way, baseball fans will enjoy the thrill of discovering what’s inside,

Our baseball mystery box collection is diverse. A mystery signed baseball is always a fun choice as you can get an autograph on a regulation MLB baseball or special-edition balls commemorating World Series championships, Silver Sluggers and Gold Gloves. Check out multiple autographed baseball jersey mystery boxes or unlock a secret signature scribbled on an authentic Rawlings bat.
