Numero 14 is a Standard-tier Dutch authenticator of signed football shirts that establishes provenance by running its own signing sessions, founded by André van der Veer and operating from the Netherlands. Its model is signed-at-source: the autograph is obtained at a session Numero 14 organises and photographs.
How Numero 14 authenticates
Numero 14 authenticates by organising the signing itself rather than judging a signature after the fact. It runs its own sessions with footballers, including players such as Robin van Persie, Jari Litmanen and Jaap Stam, and documents each with photographic proof of the signing alongside a Certificate of Authenticity. Founded by André van der Veer, the business is a Dutch session organiser whose provenance rests on having witnessed the autograph being given.
What you receive and how to verify it
The proof is the session itself: each item comes with a Certificate of Authenticity and photographic evidence of the player signing it, so a collector can match the specific shirt to the documented signing rather than relying on an after-the-fact opinion. Because Numero 14 obtains and records the autograph at source, the assurance travels with the photo proof and the COA.
Why this matters for collectors
For a collector, Numero 14's value is signed-at-source Dutch provenance: the autograph is documented at the moment of signing, with photographic proof tying it to a known session, the right assurance for items from its own signings of Dutch and visiting players. Walkouts references Numero 14 where that session-witnessed provenance is the right fit, alongside the premium bureaus it uses first for high-value pieces.
