Fine Art Certificate of Authenticity (COA) Standards: Editioning & Provenance Tracking

A Certificate of Authenticity (COA) is a legally binding provenance document that establishes the original creation, edition limit, and technical provenance of a fine art photograph.

1. Key Elements of an Archival COA

• Unique Serialized Dual Hologram System: A tamper-proof serialized hologram sticker applied directly to the COA document paired with an identical hologram affixed to the verso of the print.
• Edition Specifics: Explicit statement of edition sizing (e.g., *Edition of 10 + 2 Artist Proofs*). Once an edition closes, no further prints may ever be struck in that size.
• Technical Print Details: Paper substrate specification (e.g., *Hahnemühle Photo Rag Baryta 315 gsm*), ink or chemical process (e.g., *Silver Gelatin Selenium Toned*), and capture date.
• Artist Signature & Embossed Seal: Handwritten artist signature in archival pigment ink accompanied by a blind debossed studio seal.
