In today’s global art market — fast, digital, and highly interconnected — artists must be prepared to document their work clearly and professionally. A sale can happen quickly, but the documentation that accompanies your artwork has long-term importance. One of the most essential documents is the Certificate of Authenticity (COA).
A COA is more than a formality: it protects you, supports your collectors, and strengthens the long-term value and provenance of your work. This updated guide explains what a COA is, why it matters, and how to create one that meets professional standards.
A Certificate of Authenticity is an official document that verifies that an artwork is genuine and created by the artist named in the document.
A well-prepared COA:
Ideally, every artwork you create should have a COA, whether it has been sold or is simply part of your studio archive.
A COA gives buyers confidence that the artwork is authentic and properly documented.
It also signals professionalism and care for your artistic legacy.
With digital reproduction and AI tools becoming more sophisticated, clear documentation is more important than ever.
A COA helps establish the work’s rightful origin and reduces the risk of misattribution.
As an artwork changes hands over time, a COA becomes part of its historical record.
A well-documented provenance can support future value, insurance claims, institutional purchases, and museum loans.
COAs help you maintain an organized catalogue raisonné of your work, including sold pieces, editions, and unique works.
Below is a modern, professional checklist for what your COA should include.
Each element supports accuracy, provenance, and transparency.
Prominently placed at the top of the document.
Use the official title exactly as you present it in exhibitions, catalogues, and online listings. Consistency is essential for proper identification and future provenance tracking.
Indicate the year in which the artwork was completed. This information helps contextualize the work within your artistic practice and is particularly important for archival, curatorial, and market purposes.
Specify height × width × depth, and note whether measurements include the frame.
Be specific (e.g., “oil on canvas,” “archival pigment print,” “bronze with patina”).
Include edition size, number, and whether proofs exist (AP, PP, etc.).
Installation guidance, framing considerations, care instructions, or technical details.
A high-quality image helps with future archiving and ensures clarity when referencing the piece.
A concise declaration confirming that you are the creator of the work and retain copyright.
Example:
I certify that I am the creator of this artwork and that this piece is an authentic, original work. Copyright © [Artist Name]. All rights reserved.
Sign the COA physically or digitally using a secure signature method.
Include studio address, website, or professional email.
Artists who want to elevate their documentation may consider:
digital provenance tools (blockchain, digital tokens, etc.) if used
Make sure each completed artwork includes a COA.
