Certificate of authenticity
Verify a certificate.
Enter the code printed on your certificate to see what was authenticated, by whom, where and when.
How it works
How it works
Every piece of memorabilia we authenticate is registered with a unique code and photographic evidence. The code on the printed certificate resolves to this page — that is the record, and it is the same one the seller holds.
- 01
Every certified piece carries a code
When we authenticate a piece we register it with photographic evidence and issue a unique code, printed on the certificate that travels with the item.
- 02
Enter the code above
Twelve characters in three groups. Case and dashes do not matter — type it however you read it off the paper.
- 03
See the record itself
What was authenticated, who signed or used it, where and when, and the photographs taken at the time. The same record the seller holds.
About these certificates
What the code proves, and what it does not.
It is printed on the certificate of authenticity that came with the piece, in the format 543M-444L-543M. If the piece was bought second-hand, the seller should pass the certificate on with it.
Check for a typo first: the alphabet deliberately excludes the characters I, O, 0 and 1, so a misread produces an invalid code rather than a different valid one. If it still does not resolve, the certificate was not issued by us — get in touch before completing any purchase.
It proves that we authenticated this specific piece and recorded it, with the photographs taken at the time. Compare the piece in front of you with those photographs: the code attests to the record, and the record is what you are matching against.
To the piece. The code does not change when the item is sold, so it stays verifiable through every future owner. Anyone holding the code can open this page — there is no account and no login.
Yes. We authenticate sports memorabilia and issue the certificate together with the photographic record. Tell us what you have and we will take it from there.
