About AAS
Peace of mind from in-person autograph authentication.
Autograph Authentication Services examines signed memorabilia by hand. This website is where collectors verify authenticity with a cert number — not where photos are sent for a remote opinion.
The why of AAS
Research, validation, and a certificate you can check.
In-person examination
Paper, ink, and wear are judged with the item on the table — not from a photo you upload.
Professional research
The writing is compared with known examples of how that person signs.
An authentication opinion
Older signatures are not a perfect science. AAS gives a careful opinion after seeing the piece.
A certificate you can verify
Authentic items receive a cert number. Anyone can verify authenticity on this site later.
After authentication
You receive a certificate with a cert number. We store the signer, item type, description, and photos so a later buyer can verify authenticity against the same record.
What AAS is not
- An auction house, dealer list, or marketplace
- A service that authenticates from emailed photos
- A public directory of every certificate
- A replacement for the paper certificate you keep with the item
Sample COAs
This is what an AAS certificate looks like.
If the item is authentic, you receive a paper certificate with a cert number. Anyone can verify authenticity on this site with that number.
Verify authenticity
Enter the cert number from your paperwork. To have an item authenticated, submit your item.
