Each signature is compared to the PRO-Cert autograph exemplar library which helps confirm or deny its legitimacy. Certified items are then given a registration number and a tamper-proof hologram. Stories, photo-proofs, quantities, prior COA's, and personal reputations are NOT taken into consideration when analyzing your autograph submission. In accordance with many of the national privacy standards we do not retain customer information in regards to your submission once your order is completed.
