A sports memorabilia mystery box from Ultimate Autographs contains a real, hand-signed piece of sports memorabilia — a signed helmet, jersey, football, or photo — authenticated with a Certificate of Authenticity from PSA, JSA, Beckett, or Fanatics. Unlike blind-box sellers, we publish the player checklist for every series, so you know exactly which stars you have a chance to pull before you buy.
We've been designing autograph mystery boxes for more than a decade and have shipped them to tens of thousands of collectors. Every box is packed by our team from our own authenticated inventory — the same signed memorabilia we sell individually — which is why collectors consistently rank our boxes among the best value in the hobby.
Choose your style of rip: football mystery boxes (our most popular — signed NFL jerseys, full-size and mini helmets), jersey boxes, helmet boxes, and multi-sport mixers featuring baseball, basketball, and hockey legends. Click any series below to see its full player list.
How it works: pick a series → check the published player checklist → your box ships with the autograph inside plus its COA. Want to watch your box get ripped live instead? Join one of our daily live breaks at 9 AM, 12 PM, 3 PM, and 6 PM CT.
