Beckett graded this Jaap Stam signature 7 out of 10, on a Manchester United shirt from the 1998-1999 season, size L, signed on the back, on the number. The autograph is independently checkable against Beckett's own certified public record.

The shirt

This is Manchester United's 1998-99 home shirt, made by Umbro, in red, with the Sharp sponsor on the front, and it still carries its original tags. Two versions of this design exist: a league version with black socks, and a European version with a different collar and white socks, worn in the Camp Nou final. Collar and sock colour separate the two, worth checking on any shirt from this season.

Authentication by Beckett

Beckett has authenticated this signature with certificate AG004184, documented with a certificate of authenticity, a letter of authentication, a witnessed signing session, and a grade of 7 out of 10. The shirt carries a One Beckett Medallion hologram sticker sealing the certificate to this specific item. A collector can confirm the certificate number directly in Beckett's own database, independent of anything Walkouts states about it.

The signing

Jaap Stam signed this Manchester United shirt on 23 December 2024 in Amsterdam, The Netherlands. Walkouts logs the session under its own proof code, 24JST20016406, matched to a photograph of Stam signing the shirt that day. A collector can hold that code against the date and place it names to confirm this specific signing, independent of the certificate above.

Manchester United F.C. at UEFA Champions League

This shirt carries Manchester United's 1998-99 UEFA Champions League season, the year of the club's continental treble. United won the final at the Camp Nou on 26 May 1999, beating Bayern Munich with two stoppage-time goals from Teddy Sheringham and Ole Gunnar Solskjaer, one of the most replayed passages in the sport. The shirt design itself, the Manchester United 1998-99 home kit, is tied directly to that campaign.

For the collector

Stam's career took him through Willem II and PSV Eindhoven before Manchester United signed him in 1998, the treble-winning season this shirt represents. He had already been named Dutch Footballer of the Year in 1997 and played at the 1998 FIFA World Cup, and went on to Euro 2000 before leaving United in 2001. Owning this shirt ties a collector to Stam's own place in that season.

What You Receive: The Signed Shirt

You receive the authenticated signature, carried on the shirt, photo proof of signing, video proof of signing, sent unwatermarked after purchase, a certificate of authenticity, and a letter of authentication.

Why Walkouts

We hand you proof you can check without us. Authentication from the names collectors already trust, our own signing proof captured the moment the marker touched the shirt, and the full chain behind both, so your certainty rests on evidence you hold yourself. We've bought fakes. We know that feeling, and we built Walkouts so you never have to.

Jaap Stam, Manchester United 1998-1999 Treble Season, signed with Numero 14 COA

★★★★★ ★★★★★ 3.6 / 5.0

Signed Jaap Stam Manchester United shirt from the 1998-1999 season, authenticated and supported by signing photos.

Signed on 23 December 2024 in Amsterdam and supported by signing photos and a signature close-up, this Jaap Stam Manchester United 1998-1999 shirt carries a Numero 14 certificate of authenticity. The shirt is the red treble-season design with Sharp sponsorship and number 6 on the back, and Jaap Stam's name appears in the accompanying description. The listing includes an official player signing session image and a clear signature proof, which confirm the signing context. Condition is described as excellent and photographs show a well preserved short sleeve replica of the era. The provenance and the treble-winning season association give the shirt clear display value, and the COA plus signing documentation add verification. The listing notes that no online COA check is available, but that is covered by poto evidence.

Well authenticated signing and strong season provenance make this a notable signed football shirt, with the only caveat being the lack of an online COA check.
