Welcome to MeiGray Authenticated

MeiGray Authenticated believes in facts.

That’s why each and every jersey authenticated and marketed by the NBA & MeiGray Game-Worn Authenticated Program is photo-matched before it is offered for auction or retail sale.

That’s why each and every jersey sold through our NHL-MGG Game-Worn Jersey partnerships is affixed with a unique, counterfeit-proof, individually numbered MGG Inventory tag. This tag contains covert and overt security features and is inserted into the jersey BEFORE THE PLAYER HITS THE ICE.

That’s why every item we authenticate and sell comes with MeiGray’s Lifetime Money Back Guarantee.

MeiGray Authenticated’s team has more than 60 years of experience in the Game-Worn sports memorabilia industry. MeiGray Authenticated knows what’s real, and what opinion is. We don’t discount opinions. We just confirm those opinions with facts BEFORE we register an item.

MeiGray has a contract with Getty Images that enables us to access their extensive sports photo library. This access enables us to conclusively photo-match items worn or used by your favorite player in game action. And that’s only one way we authenticate.

As a collector, have you ever asked a dealer what research he did to authenticate a jersey? You should. MeiGray Authenticated is always ready to explain what is being done on a jersey, and how conclusions are reached, and where the research is coming from.

When it comes to research, MeiGray is talking about relying on information (inventory information from manufacturers, customizing information from teams and customizers, photos from games, videos from games) available only from the teams ... or from the Hockey Hall of Fame, or NHL Productions, or Getty Images, three organizations with which MeiGray has working relationships.

MeiGray is talking about conducting interviews with the teams, and with people who customized these jerseys 20 to 30 years ago. Through our NBA and NHL relationships, we have been able to reach these people to get certain questions answered that previously had gone unanswered ... or even unasked. And through our team partnerships, we can dig even deeper.

Of course, not all information is available. Time, and the lack of record-keeping, has prevented a lot of questions from being conclusively answered. And when answers are impossible to conclusively ascertain, and we decline to register a jersey due to lack of conclusive information, we still share information with collectors so they can make educated choices.


MeiGray maintains a database retaining information on every item it sells and/or authenticates. This MeiGrade Registration System enables collectors who purchase items in the secondary market to contact MeiGray. By using our toll-free number, 888-463-4472, and referencing the MGS Registration Number, we can confirm the relevant facts and details of the item to insure what is being offered is what we registered when we originally sold or authenticated the item.

This System of Registration enables us to issue Population Reports with teams in which we partner exclusively, and enables us to tell you how many jerseys of a particular player, or team, or year, we have registered.

We want to arm you with information before you buy from us or anybody else, to help you make informed and educated Game-Worn Jersey decisions.


Every item purchased will come with MeiGrade Registration, which includes a letter of authenticity. We believe that not all Letters of Authenticity are alike. An LOA is only as good as the integrity of the company issuing it, and the information and warranties made in it.

A MeiGray LOA tells you exactly what you have bought and the details behind the item you have bought. That’s why our LOA matters. It’s your LIFETIME WARRANTY.


We believe no two game-worn items are alike. Every item is unique: From the stitching of the names and numbers, to the fabric, to the designs and colors, to the characteristic evidence left behind by the player once the item is worn.

Every game-worn item is like a fingerprint.

MeiGray’s contract with Getty Images enables us to access their vast collection of photographs, enlarge a photo to the point where a single thread on a player’s name or number, or imperfection on a team crest, can be compared to an actual game-worn item.

That’s why we can conclusively photo-match your items. We can provide you with a color 8.5 X 11 photographic LOA that shows the match, states the place and date of the match, and adds the MGG Registration Number to your item.


MeiGray stands behind every item it sells … for life.

MGG protects the original purchaser by offering that purchaser a full refund of his purchase price at any time if a MeiGray-registered item purchased directly from MGG is conclusively proven not to be what MeiGray represented it to be.

Once an MGG-registered jersey is sold or traded in the secondary market, it becomes that person’s or dealer's responsibility to offer the warranty he or she feels is appropriate. MGG will continue to protect the original owner, and all subsequent owners, for the original purchase price. MGG will do so as long as the item has not been altered from its original condition when sold by MGG. But MGG cannot be held responsible for any secondary owner’s representation beyond the representation made by the original MGG documentation.

NOTE: This Lifetime Money Back Guarantee extends to all game-worn, game-used, and game-issued items. Since MeiGray occasionally sells non game-worn items like blank jerseys or other useable equipment, the only exception to this Lifetime Money Back Guarantee is for these non-registered items in which MGG has made no representation as to authenticity.
