Sports Autograph Mystery Boxes

Sports Mystery Boxes

While many collectors and fans prefer a sure thing, others like to take a chance. An RSA mystery box adds excitement to the quest for new memorabilia. You can see before ordering what type of collectible you’re getting and what sport it’s from, but you won’t know exactly what’s in it until you open the box. A sports memorabilia mystery box is the perfect purchase or gift for someone who loves sports and will be happy with any new keepsake. But there’s the chance you might get a souvenir signed by a hometown hero or legend of the game, and that only makes it even more thrilling.

We offer dozens of mystery combinations, from the classic autographed jersey mystery box to vintage trading cards and replica balls. If you're lucky, you might get an item that far exceeds what you paid for it — and regardless, you're still receiving a fun collectible. RSA is always adding new mystery kits, letting you write more chapters in your sports memorabilia adventures.

Random Certified Authentic Collectibles

Select a mystery sports box to see the details about what you're receiving — as many as we can provide without spoilers, that is. Our huge assortment of football and NFL mystery box sets might include signed jerseys, footballs, helmets or all the above. There are also mystery boxes for basketball, hockey and baseball fans. You can end up with baseball bats, hockey pucks, boxing gloves and many collectibles signed by the game's GOATs. Use the category options above to search for boxes from specific sports that fuel your fandom. We’ve started adding mystery boxes that cater to fanbases of certain teams, too.

Do you love all sports? You'll get a real kick from our Mystery Sports Memorabilia ANYTHING Box. It includes one random signed item from the RSA catalog for those who love a bit of a gamble. A Gold Mystery Autograph Box or Platinum Mystery Autograph Box turns the thrills and the value up to 11 by including multiple signed items. If you’re on a tight budget but still want a fun sports memento, check out our Signed Photo Sports Memorabilia Box.

Certified Sports Keepsakes

One thing is guaranteed when ordering a sports memorabilia mystery box from RSA: you'll receive genuine merchandise with autographs that are authenticated by trusted third-party services. We also have a 100% money-back guarantee against any shipping damage or other issues. (Please note that, per our policy, mystery boxes are not eligible for return.) Each box contains more value than what you’re paying, and we often have sales, too.
