PSA/DNA experts conduct ink analysis, autograph structure analysis, object evaluation and side-by-side comparisons.

Experts may also use a video spectral comparator to further evaluate the autograph.

STEP 2 – ANTI-COUNTERFEITING

Once the autograph is deemed genuine, the item is marked with invisible ink that contains a synthetic DNA sequence specific to PSA/DNA. A unique, serialized label is also provided.

STEP 3 – CERTIFICATION

Letter of Authenticity

Either a Certificate of Authenticity (COA) or a Letter of Authenticity (LOA) is issued with the genuine autograph. The document contains the same alphanumeric serial number to match the label on the item.
