SIGNATURE & ART AUTHENTICATION

Using our own proprietary database and authentication technology, PGX is able to authenticate all of your signed and/or sketched books. We can even offer you a certificate of authenticity instead of grading if you request or if your signed item is too large for us to encapsulate.

  • Signature/Art Authentication: $15.00

  • Single Book with Multiple Signatures: $15.00 for the first signature and $10.00 for each additional.

  • Witnessed Signatures: $8.00

Please feel free to contact our office about becoming an authorized signature witness.
