Certificate of Authenticity Registry

Substance Collectables Memorabilia provides an online registry that enables collectors to verify their Certificate of Authenticity. All registered items have a unique number assigned which allows collectors to verify their items by simply entering the registration number into our website. It is our mission to help collectors know that the items that they spend their hard earned money on are absolutely 100% authentic.

SubstanceCollectables.Com Certificates of Authenticity have changed over the years. Please look on your printed certificate for the number, or, your signed item may have a number on the hologram. Please check the number to verify your Certificate.

Welcome to our online collection of in-person authentic autograph examples.

Why wonder if an item is authentic when you can use our database to compare items you see for sale to known authentic in-person examples. With this ever growing database you can put an end to wondering if a seller has authentic items. Stop worrying about COAs and wasting money on authentication services by educating yourself for free.

Celebrity autographs can be very difficult to authenticate.
To help you we offer this database of known good, obtained in-person autograph examples.

SHOULD YOU NOT FIND YOUR SERIAL NUMBER - PLEASE BE PATIENT - WE ARE CONTANTLY LOGGING IN NUMBERS.
