Examination Process

Examination Process for authenticating autographs


A high powered Digital video microscope is used to analyse what type of writing instrument was used. The autograph structure is examined closely in respect to flow, slant and pressure.  The scope can also identify pre-prints, stamped and auto-pen signatures.

The type of medium is assessed.  A Proprietary light may also be used to do determine the age of the medium.

An Exemplar side by side comparison is done against a minimum of three controlled samples, often more are used.


Once the item is deemed genuine, the item is labelled with an invisible ink which contains a sequence specific to the AMA.

The item is tagged with an alphanumeric serial number in a discrete location. The same matching alphanumeric serial number is placed onto the Certificate of Authenticity.


The item is registered with a unique assigned AMA number which allows collectors to verify their items by entering the registration number into our website.

Incorporated into each items profile is who signed the item, the type of item, the type of writing device, date of authentication and a digital picture of the exact signature on the item.

Retailer Authentication

The AMA has approved the Australian memorabilia retailer, Sports Online to use certificates on products they have for sale.  For clarity purposes, products from this retailer may come with an Australian Memorabilia Association Certificate of Authenticity but has not been examined by the AMA.  The wording on the certificate would read, “This item has been approved by the Australian Memorabilia Association…” and is unlikely to have an image accompany the item in the online database.

When an item is examined physically by the AMA the Certificate would read “This item has been examined by one or more of the Australian Memorabilia Association experts…” and would be accompanied by an image of the item in the online database.
