You’re scanning eBay or hitting up a local card show and you see it: that bright "Honolulu Blue" mesh with the big number 20 or maybe the classic crimson and cream of the Oklahoma Sooners. A Billy Sims signed jersey. It looks great. The price seems reasonable. But before you pull the trigger, there is a lot of nuance to understand about one of the most electric, and tragically short-lived, careers in football history.
Billy Sims wasn't just another running back. He was a human highlight reel before social media existed. He won the Heisman in '78. He went number one overall in 1980. He basically saved the Detroit Lions from total obscurity for a few glorious years before his knee gave out in '84.
Because he is so accessible today—seriously, the guy is legendary for his BBQ chain and his fan interactions—the market for his autograph is unique. It’s not like trying to find a Barry Sanders or a Jim Brown where prices are astronomical. But that accessibility leads to a lot of "basement" jerseys and questionable "facsimiles" that trip up collectors every single day.
Why a Billy Sims Signed Jersey is a Weird Market
If you're looking for a Billy Sims signed jersey, you've probably noticed they are surprisingly affordable. We're talking anywhere from $60 to $120 for a decent custom replica. Honestly, compared to modern stars who haven't even sniffed a Pro Bowl, that's a steal for a Heisman winner.
The reason? Billy is a "good signer." He does a lot of public appearances. He has his own official shop through his BBQ business. Unlike some athletes who hide in mansions, Sims is out there. This keeps the supply steady, which is great for fans but tricky for "investors" looking to flip for a massive profit.
The Inscription Trap
When you're looking at a Billy Sims signed jersey, the signature is just the baseline. What really moves the needle are the "inscriptions."

- "78 Heisman" – This is the big one. It’s his identity.
- "80 ROY" – Referencing his 1980 NFL Offensive Rookie of the Year season.
- "Boomer Sooner" – For the OU die-hards.
A jersey with three or four of these notes is always going to be more valuable than just a "Billy Sims" scrawl. Collectors call these "stat jerseys." If you find one where he listed his career yards or Pro Bowl years, you're looking at the premium tier of his memorabilia.
Spotting the Real Deal from the Fakes
Basically, you have to watch out for two things: the "Facsimile" and the "Basement Special."
I’ve seen dozens of listings for "Billy Sims Signed Blue Jersey" that are actually laser-printed signatures. They look perfect. Too perfect. If the signature doesn't have that slight "bleeding" into the jersey mesh or that tell-tale Sharpie sheen when you tilt it in the light, keep walking. These facsimile jerseys are often sold as "gifts" for $30-$50. They aren't real autographs.
Then you have the authenticators. In 2026, the "Big Three" still rule the roost:
- JSA (James Spence Authentication): Very common for Sims.
- Beckett (BAS): You’ll see a lot of these from private signings.
- PSA/DNA: The gold standard for many, though often pricier.
If a jersey has a COA (Certificate of Authenticity) from a company you’ve never heard of, or just says "guaranteed authentic by the seller," be careful. Billy does a lot of work with "Schwartz Sports" and his own "Billy Sims BBQ" store. Those are generally ironclad. If the signature looks "shaky," it might just be age, but usually, Billy has a very fluid, consistent hand.

The Custom vs. Authentic Jersey Debate
Here is where people get confused. Most Billy Sims signed jerseys you see for $80 aren't "official" Nike or Mitchell & Ness jerseys. They are what the hobby calls "Custom Replica" jerseys.
These don't have team logos. They don't have the "Lions" or "Sooners" branding on them because of licensing costs. They are basically just blue or red jerseys with numbers and a nameplate.
Is that a problem? Not really. Most people frame them anyway. Once it’s behind glass, you can’t tell it’s a generic brand. But if you want a "true" jersey—like a vintage 1980s Sand-Knit style or a high-end Mitchell & Ness throwback—expect to pay $300 or more for the signature on top of the garment's value.
What Really Happened With the Knee?
To appreciate the jersey, you have to appreciate the tragedy of 1984. Sims was at the peak of his powers. On October 21, 1984, against the Minnesota Vikings, he took a hit that basically exploded his right knee. It wasn't just a "tweak." It was a catastrophic injury that ended a Hall of Fame trajectory.
He finished with 5,106 rushing yards in just 60 games. That’s an average of 85 yards per game. For perspective, that’s a higher career average than many Hall of Famers. When you hold a signed jersey, you're holding a "what if" story. That’s why the Lions eventually retired his #20, which was later famously worn by Barry Sanders (with Billy’s blessing).

Actionable Tips for Collectors
If you are ready to buy, don't just jump at the first listing. Follow these steps to make sure you're getting something worth hanging on your wall:
- Check the Ink: Look for silver paint pen on dark jerseys. It pops much better than black Sharpie, which tends to fade or "sink" into the fabric over time.
- Verify the Hologram: Go to the authenticator's website (like Beckett or JSA) and type in the serial number on the sticker. If the description doesn't match a "signed jersey," it’s a swapped sticker.
- Oklahoma vs. Detroit: The Sooners jerseys generally hold value better because his college legacy is untarnished. He’s a god in Norman. In Detroit, he’s a legend, but Barry Sanders casts a long shadow over the #20.
- Avoid "Raw" Autographs: Unless you’re buying it directly from his official BBQ site, do not buy an unauthenticated jersey. It isn't worth the $20 you think you're saving.
The market for Billy Sims is stable. It isn't going to make you a millionaire, but as a piece of football history, it’s one of the most satisfying "bang-for-your-buck" items you can own. Just make sure the "78 Heisman" is written clearly—that’s the mark of a true Sims classic.
To ensure your investment stays protected, always display the jersey in a UV-protected shadow box. Direct sunlight will turn a vibrant Billy Sims signature into a faded ghost of a memory within a few years. Frame it right, and you have a permanent tribute to the man who made the "Billy Sims Jump" famous.
