To combat counterfeiting and provide peace of mind to collectors, PSA/DNA employs a four-level Authentication System. The process includes:
Each photograph is examined to determine if it was made from the original negative, a duplicate negative or a wire transmission. The stampings on the reverse of the photograph are identified in order to date the photograph to the approximate era of production. As a final step of analysis, each genuine photograph is given a classification from Type 1 to Type 4 based on its characteristics.
Covert Tagging - Once the photograph is authenticated by one or more PSA/DNA experts, the item is marked with invisible ink which contains a synthetic DNA sequence/combination specific to PSA/DNA.
The DNA-laced taggant can only be detected in a scientific lab or with a proprietary infrared laser. In fact, by using the laser, the invisible DNA-ink will glow "GREEN." More importantly, the chance of replicating this exact sequence is 1 in 33 trillion!
Overt Tagging - A label bearing an alphanumeric serial number is applied on the back of the item in a discrete location away from any inscription, notes or stampings or on the Letter of Authenticity. The choice is yours. Interestingly enough, this label was specifically designed to checkerboard when tampered with and can be completely removed! In addition, the label is non-destructive and does not harm your valuable item.
Letter of Authenticity - A detailed letter on your authenticated piece is composed and issued with your item. The letter provides several security features to prevent counterfeiting:
All authenticated memorabilia is available online for verification. Simply visit Cert Verification and enter the alphanumeric serial number. The verification page will display (if applicable):
Photographs that do not meet our requirements in our opinion, and are of questionable authenticity will receive a "NO PASS" designation. Thereafter, a Letter of Opinion (LOO) is returned with an explanation of our experts' findings.
Occasionally, our experts cannot express an opinion on a photograph. These will be designated as "Inconclusive" and a credit voucher will be issued in the full amount of the authentication fee. This voucher can be used towards future submissions.
Autographed Photos: Autograph and Original Photograph Authentication are separate services. In order to have the autograph authenticated, you must fill-out a separate PSA/DNA authentication submission form, in addition to your Original Photograph submission form. Both submission forms must accompany the photo. Separate authentication fees apply.
