Art Authentication and Certificate of Authenticity (C.O.A.)
An art authentication or Certificate of Authenticity (C.O.A.) is issued exclusively by a solely recognized authenticator—an expert widely acknowledged by major auction houses and institutions as the definitive authority on a specific artist.
Who is a Solely Recognized Authenticator?
Expertise: Certifies whether an artwork is authentic or not.
Recognition: Their authority is internationally accepted by auction houses and collectors.
Background:
Often someone closely associated with the artist (e.g., Paloma Picasso for Picasso artworks).
May be a family member, a trusted collaborator, or an organization with extensive experience in studying the artist’s work (e.g., Julius Held for Peter Paul Rubens; now the Rubenianum in Antwerp).
Authentication Challenges for Old Masters
Authorship authentication for Old Masters like Rembrandt or Raphael is complex.
Often requires consensus from multiple leading experts.
Process duration: 5+ years, with significant costs involved.
Requirements for Authentication
A. Photographic Documentation
Required Photos:
3 black-and-white photos (5” x 6” or similar).
3 color photos (5” x 6” or similar).
High-Resolution Digital Images:
Large, professional-quality digital photos on a USB drive (replacing older Ektachrome transparencies).
Professional Quality: Photos must be taken by a professional photographer.
B. Supporting Documents
Provenance:
A verifiable history of ownership.
Examples: Photos, letters, or other tangible proof.
Statements alone (e.g., “I received this from Picasso in 1957”) are insufficient without documentation.
Condition Report:
Detailed report outlining restoration history and current state of conservation.
Back of Artwork:
High-quality photos of the back, including annotations, patches, or restorations.
Purchase Records:
Bills of sale or other documentation proving acquisition.
