How to Tell If a Jersey Is Real (and If the Signature Is)

You can tell if a jersey is real by checking four things: the league shield at the collar, the jock tag at the bottom front hem, how the numbers and patches are attached, and the price. A real Nike NFL jersey has a molded NFL shield at the point of the V-neck, a woven jock tag with the NFL shield, the NFLPA mark, the size and the swoosh, clean even stitching on every sewn piece, and a price close to what the team shop charges.

If the jersey is signed, there's a second question, and it's the one that decides what the thing is worth: is the autograph real? A jersey can pass every check below and still carry a forged signature. We'll get to that after the fabric.

First, a custom isn't a fake

This is the part most guides miss, and it's the one we see trip people up every week. Most signed jerseys aren't official jerseys at all. They're customs: a blank made in the team's colors with the player's name and number sewn on, and no league or team logos anywhere.

Right now we've got about 1,700 signed football jerseys in stock. More than 1,200 of them are customs. About 110 are Nike or Mitchell & Ness. A custom sold as a custom is an honest product, and it's how a lot of fans get a real signature on the wall for $80 to $150 instead of $400 and up.

So a jersey with no logos isn't a fake. A jersey with logos it has no right to wear is. That's the whole line. A seller who puts an NFL shield and a swoosh on a blank and calls it a Nike jersey is selling a counterfeit, and the checks below are how you catch it. If you're weighing a custom against a licensed jersey on purpose, our breakdown of custom vs licensed signed jerseys covers what the difference costs you.

Check the collar

Start at the neck, because it's the fastest tell and the one counterfeiters most often get wrong. Every Nike NFL jersey we pulled up for this post has the NFL shield sitting at the point of the V-neck, set into the collar trim. It's a crisp, molded piece with sharp edges and readable lettering.

On a knockoff the shield is the usual giveaway. It's a flat embroidered patch, a print, or a blurry shape where the stars and the football run together. Nike has made NFL jerseys since 2012, so a "Nike" jersey for a current team without that shield at the collar is a red flag.

Read the jock tag

The jock tag is the woven label at the bottom front of the jersey, just above the hem. On a real Nike NFL jersey it's a dark panel with the NFL shield, the NFLPA mark for the players' association, the size, the swoosh and a line that reads "engineered to the exact specifications of the National Football League."

Two things to look for. The lettering should be sharp enough to read at a glance, and the tag should be sewn down flat and straight. Blurry text, a misspelled word, a tag stitched on crooked or a jersey with no tag at all are the signs the federal agents who seize fakes every year tell fans to watch for. Their guidance, published with the 2025 Super Bowl seizure, names "sloppy stitching" and missing security labels first.

The tag also tells you the tier. Nike's Game and Limited jerseys use letter sizes like XL, and the Elite uses numbered sizes like 48. Our guide to replica vs authentic jerseys walks through that side by side.

Look at the numbers and the stitching

How the name and numbers are attached depends on the tier and the season, so this check is about matching the real thing rather than one right answer. Nike's entry Game jersey has flat printed numbers. The higher tiers use sewn twill or heat-applied numbers depending on the year, and even our own shelf has both. Find the same tier and season in the official shop and make sure the numbers on the jersey in front of you are built the same way.

Whatever the method, real ones are neat. Stitched numbers have tight, even edges and sit flat without puckering. Printed numbers have no bubbles, no peeling corners and no fuzzy outlines. Turn the jersey inside out too. Real jerseys are clean on the inside, and fakes often show loose threads and messy backing behind the numbers.

One correction while we're here, because it's on a page that ranks for this exact question: Nike's tiers go Game, then Limited, then Elite, from cheapest to most expensive. The Elite is the top of the line, not the bottom.

Check the font, the colors and the details

Every team has its own number font, outline and colors, and they change with uniform updates. Pull up the team's current jersey in the official shop and compare. Fakes tend to miss on the small stuff: a number font that's slightly too thin, an outline in the wrong shade, a sleeve stripe that doesn't match, or a "current" jersey for a player in a uniform the team retired years ago.

The price and the seller

This is the check that catches most fakes before you ever touch the jersey. A blank Nike Game jersey runs about $150 at the league shops, a Limited about $175 to $200 and an Elite about $400. A brand new "Elite" for a fraction of that isn't an Elite.

The seller tells you a lot too. Be wary of a listing with every size and every star player at the same low price, stock photos instead of pictures of the actual jersey, or a seller who won't show you the jock tag. The scale here is real. Ahead of the 2025 Super Bowl, federal agents and the leagues announced they'd seized 214,507 counterfeit items worth $39.5 million, from jerseys to hats to memorabilia.

A real jersey doesn't mean a real autograph

Here's the part that matters most if you collect. Everything above tells you whether the fabric is legit. None of it tells you whether the signature is. A forger can sign a perfectly real Nike jersey, and plenty of them do, because buyers who've just checked the collar and the jock tag tend to relax.

For a signed jersey, the check that counts is the certificate and the hologram. A legitimate signed jersey carries a serial-numbered hologram from a third-party authenticator like PSA/DNA, JSA, Beckett or Fanatics, usually stuck right on the jersey near the signature, with a matching certificate. Look the serial up in that company's own online database and make sure the record describes a jersey, the right player and the right item, not a photo or a ball.

We don't authenticate anything ourselves. We're a dealer, and we rely on those third-party authenticators for every signed item we sell. We also won't sell a signed jersey that isn't authenticated, custom or licensed. Our guide to how to tell if an autograph is real covers the signature side in more depth, and our authentication page explains how the major authenticators work.

The quick checklist

• Collar: a crisp, molded NFL shield at the point of the V on a Nike NFL jersey.
• Jock tag: sharp lettering, sewn flat and straight, with the shield, NFLPA mark, size and swoosh.
• Numbers: built the same way as the official version of that tier and season, and neat either way.
• Details: font, outline and colors match the team's current official jersey.
• Price and seller: close to retail, real photos, happy to show you the tag.
• If it's signed: a third-party hologram whose serial looks up to a jersey record.
