Certificate of Authenticity

The Certificate of Authenticity (COA) is an essential document that you must provide in the event of a sale of your artwork.


It is an official document that proves your work is genuine and authentic. It proves a work’s provenance and quality and assures a buyer that it is produced by you and no one else. It is also a form of risk-prevention regarding forgery and counterfeit. Ideally, it should accompany every work of art, regardless of whether it is sold or not.


It also acts as a sales receipt, and in the event that your work increases in value over time, a COA acts as a physical document that tracks the provenance of your works, thus proving an increase in value.


Many artists wonder where to even begin composing this crucial document. We have provided a professional template for you here.
