Free certificate of authenticity template

A certificate of authenticity, or COA, is a document from the artist confirming that a work is genuine. It records who made the work, what it is and when it was made, and carries the artist’s signature. Collectors, galleries and buyers keep it with the work as proof of its origin.

The artist’s name, the title of the work, when it was made, its medium and dimensions, edition details for prints, a statement that the work is authentic and the artist’s signature. A photo of the work makes the certificate easy to match to the piece.
