📄 Certificate of Authenticity (COA)
At Rosen Appraisals, we understand how vital authenticity is to the value, trust, and legacy of fine art. Our Certificate of Authenticity (COA) service offers collectors, galleries, museums, and estates a formal, professionally prepared document certifying key details of a work of art’s authorship and origin.
Whether you are preparing a piece for sale, exhibition, insurance, or legacy planning, our COAs help strengthen provenance and increase buyer confidence.
✅ What Our COA Includes:
Artwork title, medium, dimensions, and creation date (if known)
Artist attribution and supporting evidence
Provenance summary (ownership history)
Reference to catalogue raisonné (when applicable)
High-resolution image of the artwork
Signed documentation on Rosen Appraisals letterhead
Appraiser’s statement and date of issue
⚠️ Please Note:
While Rosen Appraisals conducts thorough research and due diligence, COAs are issued based on the information available at the time of review. For works requiring full scholarly authentication or inclusion in a catalogue raisonné, we offer referral services and documentation support.
Ideal For:
Collectors managing private collections
Estates compiling legacy documentation
Institutions formalizing archival records
Galleries authenticating art
