Jaap Stam's number 6 shirt from Manchester United F.C.'s 1998-1999 season, in a size XL, carries his signature. Beckett awarded the signature a grade of 7 out of 10 after Stam signed it in Amsterdam in December 2024, and the authentication is independently verifiable.

Manchester United's 1998-99 home kit in red, number 6

This home shirt is red, made by Umbro, with the Sharp sponsor printed across the front of Manchester United's 1998-99 kit. It is a signed shirt, its value resting on Stam's authenticated signature. The signature sits on the number 6 on the back, the shirt is a size XL, in very good condition, and the original tags still remain attached.

Authentication by Beckett

Beckett issued a certificate for Stam's signature on this 1998-99 Manchester United shirt, and the paperwork with it records the signing as witnessed. The certificate also records a signature grade of 7 out of 10, the authenticator's assessment of the autograph itself. Beckett's authentication label on the shirt is an iridescent hologram disc sticker, and a collector can match it against the certificate's own description of the label.

Signed in Amsterdam, December 2024

Stam signed this particular shirt on 23 December 2024, during a private session held in Amsterdam, the Netherlands, which Walkouts logged under proof code 24JST20016306 as its own record of the session. The photography taken that day shows him wearing a black zip jacket, seated at a memorabilia table, signing the red shirt at the point where 'STAM 6' is printed on the front.

Manchester United at the UEFA Champions League

Manchester United's run through the 1998-99 UEFA Champions League finished at the Camp Nou on 26 May 1999, where two stoppage-time goals from Teddy Sheringham and Ole Gunnar Solskjaer beat Bayern Munich and sealed the treble, an English first. United ended that European campaign as champions of the competition.

Dutch Footballer of the Year, 1997

A centre-back, Stam's path ran from Willem II through PSV Eindhoven to Manchester United, where he stayed until 2001. He was named Dutch Footballer of the Year in 1997 and appeared at the 1998 FIFA World Cup, the honour and the tournament appearance behind an established international defender. His signature on this shirt ties a collector to that standing, the shirt representing the 1998-99 season.

Signing video

You receive the authenticated signature, carried on the shirt, with the witnessed signing session record. Photographs of the signing and the video of the signing come with it, the video sent to you without a watermark after purchase.

Jaap Stam, Manchester United 1998-1999, signed shirt, Beckett COA BS92799

★★★★★ ★★★★★ 4.2 / 5.0

Beckett-graded signing from a witnessed session on 23 December 2024, signed on the No. 6 and presented as a short-sleeve XL football shirt.

Beckett-certified with COA number BS92799 and grade 7, supported by a witnessed signing session with photo proof and video proof on 23 December 2024 in Amsterdam, The Netherlands. The shirt is signed by Jaap Stam on the printed No. 6 on the back, and photos show the short-sleeve red shirt with the Umbro crest and SHARP sponsor to the front. The Premier League 1998-1999 season provides the historical anchor for the styling and squad number, and the presentation is suitable for framing behind UV-safe glass or for careful folded storage with acid-free tissue. What matters here is the documented signing and third-party grading that link the autograph to a specific session and to Beckett's evaluation. The shirt is offered as a signed display item rather than a match claim, and the condition appears consistent with a fanshop style short-sleeve shirt in size XL. A caution applies, there is an online COA check available.

A clear signed Jaap Stam shirt with third-party grading that suits display and focused Manchester United collections, best for buyers seeking certified signing provenance.
