Who Authenticates Sports Autographs? The Companies Behind a COA

A certificate of authenticity only means something if you know who issued it. The sticker is easy to fake. The database behind it isn't, and that database is the whole point. Here's who actually certifies signed sports memorabilia, what each company is good for, and how to check a certificate yourself in about thirty seconds.

The four names you'll actually run into

PSA / DNA started in 1998 and it's the biggest authentication operation there is, by a distance. The scale is hard to picture until you see a monthly number: PSA graded roughly 2.5 million items in June 2026 alone. Its free cert lookup covers every autograph it certifies.

JSA (James Spence Authentication) opened in 2005 under James Spence Jr., and the Spence family has worked in autographs across four generations. JSA is the name you'll see most often on vintage single-signed baseballs and older paper, which is the hardest category to get right.

Beckett Authentication Services (BAS) launched in November 2016, which makes it the youngest of the four, though Beckett itself has been pricing collectibles since the 1980s. Steve Grad, who most people know from Pawn Stars, ran authentication there from the start and moved into an advisory and training role in March 2026. Brian Sobrero remains one of the principal authenticators.

Fanatics Authentic is the odd one out, because it mostly certifies signings it arranged itself. When Fanatics has an athlete under contract, its own witness is in the room, the hologram goes on before the item leaves, and the FanSecure database records it. That's a different kind of proof from an expert examining a signature after the fact, and for modern athletes it's the strongest kind there is.

Upper Deck Authenticated still runs too, on the same witnessed model it started in 1992, and its hologram database is still searchable. You'll see UDA mostly on a small group of athletes it signs exclusively.

How to check a certificate in thirty seconds

Every one of these companies publishes a free lookup. You don't need an account and you don't need to ask the seller for anything except the number.

• psacard.com/cert
• spenceloa.com certification verification
• beckett-authentication.com verify certificate
• fanatics.com/fansecure
• upperdeck.com hologram database

Type in the serial and check that the record describes the item in front of you. Right player, right item, right sport. A serial that returns nothing, or returns a different item, is the end of the conversation. Do this before you pay rather than after, and do it on the authenticator's own website rather than through a link the seller sends you.

Steiner Sports is gone, and that matters if you own one

For two decades Steiner was one of the biggest names in the business, especially for New York athletes. It isn't one now. Fanatics bought the bulk of Steiner Sports in 2019, and Steiner filed a closing notice with New York State that October covering all sixty of its employees.

The practical problem is what happened to the old records. Collectors have reported that Steiner serial numbers from before the sale often return nothing in the current database, which leaves people holding a legitimate item with a certificate they can no longer confirm online. If that's you, keep every piece of paperwork and the original hologram, and expect to explain the history when you sell. If a seller offers you a Steiner-certified item today, price that friction in.

The wider lesson is worth holding on to. A certificate is a promise from a company, and companies get bought and shut down. That's part of why the authenticator's name on a COA matters as much as the COA itself.

What we put on our own items

We don't authenticate anything ourselves. We're a dealer, and we think a dealer certifying its own inventory is the thing collectors should be most suspicious of across this whole industry. Everything we sell is certified by one of the outside companies above before it's listed, and we won't list a signed item that isn't.

In practice the catalog leans heavily one way: about four out of five items we stock carry a Beckett COA, with JSA and Fanatics making up most of the rest. You can see how that works across our signed helmets, football jerseys and mini helmets, and we lay out the whole process on our authentication page.

What a COA doesn't tell you

A certificate answers one question: did this person sign this item. It says nothing about condition, nothing about rarity, and nothing about what the item's worth. Plenty of certified items are worth less than their owners think, and the certificate won't argue with you about it.

For the rest of it, start with what a COA is and how the hologram system works, then how to spot a signature that's wrong and what goes wrong when you buy uncertified.
