Photograph Authentication Process
To combat counterfeiting and provide peace of mind to collectors, PSA/DNA employs a four-level Authentication System. The process includes:
STEP 1: Examination
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.
- Type I - A 1st generation photograph, developed from the original negative, during the period (within approximately two years of when the picture was taken).
- Type II - A photograph, developed from the original negative, during the period (more than approximately two years after the picture was taken).
- Type III - A 2nd generation photograph, developed from a duplicate negative or wire transmission, during the period (within approximately two years of when the picture was taken).
- Type IV - A 2nd generation photograph (or 3rd or later generation), developed from a duplicate negative or wire transmission, during a later period (more than approximately two years after the picture was taken).
- Type 1 photographs are the most desirable and valuable of the four photograph types because of their vintage and originality.
- Many Type 4's were issued after 1970, either for latter-era publication of earlier original images or for the general public consumption.
- Duplicate negatives are produced by taking a photograph of an existing original photograph thereby creating a second negative that is of inferior quality to the original
- All photograph types are collectible; a Type 3 photograph of a Hall of Famer Mickey Mantle may be worth considerably more than a Type 1 photograph of a common player from the 1920's.
STEP 2: ANTI-COUNTERFEITING
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.
STEP 3: CERTIFICATION
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:
- Double-watermarked paper; simply hold the LOA against a lamp and look for the official PSA/DNA logo and a series of double helix DNA strands.
- A detailed, color-changing PSA/DNA logo hologram embedded into the custom paper: not a sticker placed on top of the page, but rather actually part of the paper itself.
- A high resolution photo of your item.
- Hand signature from one of PSA/DNA's representatives.
- A report of the expert's findings.
- Seven digit alphanumeric serial number that matches the tamper evident label.
STEP 4: DOCUMENTATION
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):
- The Item
- Primary Subject
- Type Classification
- Photo Genre
- Item Era
- Item Image
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.
