Certificate of Authenticity (COA)

Certificate of Authenticity (COA)

A Certificate of Authenticity (COA) is a document that accompanies a piece of artwork to verify its authenticity.

The COA is typically issued by the artist, the gallery, or the publisher and includes details like the edition number, the size of the edition, and the materials used. It serves as a guarantee of the work's authenticity and can be important for valuation and resale. A COA provides collectors with the assurance they need when investing in a piece of art, adding credibility and value to the artwork.
