Certificates of Authenticity: What Artists Should Include
Artist & Gallery Resources
By Mark Shapiro | The Art Fair Advantage
One of the easiest ways for artists and galleries to appear more professional is by providing a Certificate of Authenticity.
Yet surprisingly, many artists either do not provide one at all or create certificates that are missing important information.
After more than 40 years in the art world, I have learned that collectors appreciate documentation.
It creates confidence.
It supports provenance.
It reinforces the professionalism of both the artist and the gallery.
Think of a Certificate of Authenticity, often called a COA, as the birth certificate of the artwork.
It tells the story of what the artwork is, who created it, and when it entered the collection of its new owner.
Why Does a Certificate Matter?
Collectors purchase artwork for many reasons.
Personal enjoyment.
Home decoration.
Corporate collections.
Estate planning.
Future resale.
Insurance purposes.
A professional certificate helps support all of these objectives.
It also reassures buyers that the artwork was acquired directly from a legitimate source.
Good documentation helps protect the collector, the artist, and the future history of the work.
What Should Be Included?
Every Certificate of Authenticity should contain clear, accurate information.
At a minimum, include the following:
Artist Name
Use the full name of the artist.
This should match the way the artist signs, presents, and promotes their work professionally.
Artwork Title
Include the official title of the artwork.
Be consistent across the certificate, invoice, inventory list, website, and artwork label.
Medium
Clearly identify the medium.
Examples may include:
Oil on canvas
Acrylic on panel
Watercolor on paper
Bronze sculpture
Mixed media
Archival pigment print
Screenprint
Photographic print
Be specific.
Collectors appreciate clarity.
Dimensions
Include the dimensions of the artwork.
For paintings, drawings, and prints, include image size or artwork size.
If applicable, also include framed size.
For sculpture, include height, width, and depth.
Year Created
Include the year the artwork was completed.
This helps establish the timeline and history of the work.
Edition Information
If the artwork is a limited edition, include all edition details.
This may include:
Edition size
Edition number
Artist proof designation
Printer’s proof, if applicable
Publisher information, if applicable
For example:
12/50
This means the artwork is number 12 from an edition of 50.
Edition information should always be clear and consistent.
Artwork Image
Include a small color image of the artwork on the certificate.
This helps identify the specific piece and reduces confusion later.
The image does not need to be large, but it should be clear and accurate.
Artist Signature
The certificate should include the artist’s signature.
This may be an original signature on a printed certificate or a verified digital signature for a PDF certificate.
Whenever possible, an original signature adds a personal and professional touch.
Date of Issue
Include the date the certificate was created or issued.
This is especially helpful for documentation, resale, and collector records.
Additional Information I Recommend
Over the years, I have found it helpful to include several additional details when appropriate.
These may include:
Collection or portfolio name
Inventory number
Studio location
Gallery name, if represented
Website
Email address
Special notes about the work
Care or handling instructions
Framing information
Printing process
Paper type
Archival materials
For limited editions, I recommend mentioning the printing process and paper type whenever appropriate.
For example:
Archival pigment print on cotton rag paper.
That kind of detail helps collectors understand quality.
Make It Professional
Your certificate should reflect your brand.
Use:
Your logo
Consistent fonts
Clean spacing
Professional layout
High-quality paper or PDF presentation
The certificate should feel like an extension of your artwork.
It should not look like something quickly typed the night before the sale.
A professional certificate tells the collector that you take your work seriously.
Keep Copies for Your Records
Always maintain a digital archive.
Store:
Certificate number
Buyer information
Sale date
Artwork image
Invoice copy
Edition information
Contact information
Delivery or shipping details
Years later, this information can become incredibly valuable for provenance, collector support, resale inquiries,
insurance questions, or estate planning.
Do not rely on memory.
Create a system and use it consistently.
My Final Thought
A Certificate of Authenticity is more than a piece of paper.
It is a professional promise.
It tells collectors that you care about your work, your reputation, and their investment in your artistic journey.
Create one for every sale.
Keep a copy for your records.
And treat documentation as part of the collecting experience.
You will be glad you did.
See you on the show floor.
