A certificate of authenticity (CoA) is a document to demonstrate that the item is authentic.

Certificate of Authenticity

CoAs are most common in the art world. Generally speaking, a valid CoA for an artwork will include specific details about the artwork like when and how it was produced, the names of people or companies involved in the artwork’s production, the work’s exact title, the dimensions of the art, and the names of reference books, magazines, or similar resources that contain either specific or related information about either that work of art or the artist.

The CoA should also state the qualifications and full contact information of the individual or entity that authored the certificate with his or her complete and current contact information.


Facts about my CoA:

  • All my certificates of authenticity are original documents, hand-signed by me – NOT photocopies
  • A legitimate certificate of authenticity must fully and accurately describe the work of art which it is authenticating, including size, medium (limited edition print), date, title, edition size and CoA#. There should be no doubt that the CoA describes one and only one work of art. All my CoA meets all of these criteria
  • You can request and review the complete CoA and not just a portion of it before buying my artwork
  • If you have any questions about a certificate of authenticity, please contact Tadej.photo for the answers BEFORE you buy my artwork. Thank you
