The shirt features number 6, worn by Jaap Stam during the legendary 1998-99 treble-winning campaign when Manchester United won the Premier League, FA Cup, and Champions League.

This shirt was signed by Jaap Stam on 23 December 2024 in Amsterdam, The Netherlands during an official signing session and authenticated by Beckett, with signing photo, video proof, and signature proof providing comprehensive visual documentation. The Beckett certificate of authenticity with certification number BS92799 and autograph grade 7/10 provides premium third-party verification, creating authentication for collectors of Manchester United history and legendary defenders.

The shirt is a size XL in excellent condition, featuring Manchester United's classic 1998-99 home design with club crest and manufacturer details. The number 6 and STAM nameset represent the classic Manchester United styling from this historic treble-winning season.

The 1998-99 season saw Manchester United achieve the impossible treble, winning the Premier League, FA Cup, and Champions League. Jaap Stam was a defensive rock throughout the campaign, forming a formidable partnership with Ronny Johnsen and helping United keep crucial clean sheets. The Champions League final on 26 May 1999 saw United defeat Bayern Munich 2-1 with two injury-time goals, completing one of football's greatest achievements. This 1998-99 shirt represents the Rots van Kampen (Rock of Kampen) at the peak of his powers during football's most legendary season.

Jaap Stam is one of football's greatest defenders. Born on 17 July 1972 in Kampen, Jakob Stam earned the nickname Rots van Kampen (Rock of Kampen) for his defensive solidity. His achievements include winning the UEFA Champions League with Manchester United in 1999 as part of the historic treble, three Premier League titles, and reaching the 1998 World Cup semi-final and Euro 2004 semi-final with Netherlands. He earned 67 caps for Netherlands and is regarded as one of the best defenders of his generation. Known for his strength, pace, and reading of the game, Stam was a dominant force in world football. This 1998-99 shirt represents his greatest achievement.

The Beckett certificate of authenticity with certification number BS92799 and autograph grade 7/10 provides premium third-party verification for collectors. The Beckett LOA confirms the signature authenticity and provides online verification at beckett-authentication.com. The autograph grade of 7/10 reflects good signature quality, while the comprehensive signing proof documentation creates high-level authentication for legendary player memorabilia from football's greatest season.

The 1998-99 campaign represents the pinnacle of English football, with United achieving what no English club had done before. Stam's status as a treble winner, Champions League winner, and Netherlands legend creates exceptional historical significance. As one of the greatest defenders of his generation, authenticated memorabilia from this legendary treble season creates compelling value for collectors of Manchester United history and football's greatest achievements.

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.
