Jorthy Mokio signed this AFC Ajax 2024-2025 Fanshop Authentic shirt, number 31, during a session in Amsterdam in April 2025. Beckett graded the signature 9 out of 10, the first Mokio autograph the authenticator has certified, and it is independently verifiable.

Ajax's 2024-25 home kit in red and white, number 31

Adidas manufactured this Ajax home shirt in red and white during the 2024-25 season it represents, releasing it as part of that year's original retail run. It is a size M in mint condition, with the original tags attached inside the collar, where the size and care label confirm the fit. Mokio's signature sits beside the number on the back.

Authentication by Beckett

Beckett issued a certificate for Mokio's signature on this Ajax shirt from the 2024-25 season, after a signing session carried out with a witness present, and graded the signature 9 out of 10. An iridescent hologram disc sticker from Beckett is fixed to the shirt's fabric, the certification's physical mark on this specific piece, separate from the certificate's own paperwork.

Signed in Amsterdam, April 2025

Mokio signed this shirt during a session in Amsterdam, the Netherlands, on 20 April 2025, with Walkouts present throughout. He wore a maroon hoodie for the signing, and framed match photos hung on the wall behind him as he signed the shirt printed MOKIO and number 31. Walkouts assigned the shirt its own proof code, 25JMO20019731, as Walkouts' record of that specific signing.

2024-25 season at Ajax

Mokio's 2024-25 season for Ajax included his Belgium senior international debut, on 20 March 2025 against Ukraine at 17 years and 19 days old, one of Belgium's youngest ever internationals. He also started his first Eredivisie match that season, on 9 February 2025 against Fortuna Sittard, the second youngest player to start a league match for Ajax.

Eredivisie first start

The shirt belongs to the 2024-25 season it was produced in, the same year Mokio's signature was added, giving it standing as a genuine piece of that period alongside the authentication. He made his first Eredivisie start that season, against Fortuna Sittard on 9 February 2025. Weeks later, his volley against Union Saint-Gilloise on 13 February 2025 made him the youngest scorer in Europa League knockout stage history.
