While a Certificate of Authenticity (COA) is the most common way to verify a work, several other specialized documents describe and validate different aspects of an artwork’s history, value, and physical state.
A Certificate of Authenticity (COA) is a signed paper that attests
that a piece of art is genuine and was created by the attributed
artist. It’s like a “passport” or ID Card for the artwork, giving
essential details and showing its provenance and background
which may include the documented history of ownership.
Usually, COA’s with more detail can command more money for
the art because it authenticates the work.
Beyond simple authentication, professional collectors and galleries use these specific reports to build a complete profile of a piece:
Letter of Provenance (LOP): This document tracks the history of ownership. Unlike a COA, which just says “it’s real,” an LOP provides a roadmap of every owner, gallery, and exhibition the work has passed through, which can significantly boost its market value.
Condition Report: A detailed technical document that records the physical state of the artwork at a specific moment. It notes any damage, fading, or previous restoration work and is essential before shipping or insuring high-value pieces.
Appraisal Report: An expert’s opinion on the monetary value of the piece. There are different types based on your needs, such as Fair Market Value (for selling or taxes) or Replacement Value (for insurance).
Artist Statement: A narrative written by the creator that describes the inspiration, meaning, and intent behind the work. While not a legal “certificate,” it is often required for academic or gallery submissions to provide context to the art.
Further documents like a COA or Special Reports provide investment protection, proof of authorship and a bit of professionalism too. Authenticated
works often have higher resale prices and are attractive to
collectors and auction houses.
But actually COA’s are most reliable when they come directly from the
artist, their estate, or an authorized gallery or Auction House.
They can also be issued by recognized authentication boards,
specialty appraisers or experts in the field.
Be aware that because anyone can technically print a COA, they can be forged. So, it is important to check the credentials of the issuer and where it comes from
especially for higher value purchases.
Some things to consider when evaluating COA’s and Special Reports:
It is important to understand the nuance in documentation…
What is the wording? Is it an expert opinion? What’s the scope
of authority? What is the COA’s value in the Market?
The Wording: Does the Certificate say for example, “By
Pablo Picasso” authentic by the artist or “Attributed to Pablo
Picasso”(The latter is a more cautious scholarly opinion)
Expert Opinion: A credible appraiser or historian often
issued certificates stating a work was “attributed” to an artist,
especially in artists like Pablo Picasso for example.
Scope of Authority: An appraiser and historian, could
certify that a painting or artwork is consistent with a
master’s style and era, but for world-famous artists (like
Picasso), he may not be the official legal authority
required for absolute authentication (which typically
resides with family estates or specific committees).
Value in the Market: Despite this, certificates can be highly
respected in the art market, as they offer a professional
historian’s or experts verification of a work’s legitimacy and
origin.
When You Can Buy Without a COA:
Direct from the Artist: If you know the artist personally or are
purchasing directly from their studio, a bill of sale can suffice.
Reputable Dealer/Gallery: An invoice from a reputable dealer
or auction house that explicitly guarantees the work’s
authenticity acts as a valid substitute for a formal COA.
Older Artwork: For historic, secondary market pieces, a COA
may not exist, requiring expert appraisal instead.
What to Look For Instead…
If a COA is not provided, ensure you have a formal bill of sale,
provenance documents (records of ownership), or a recognized
expert’s appraisal.
The Letter of Transmittal:
The latest inclination is to try to get a letter of transmittal,
especially if you feel strongly about the art. There are
professionals with experience in the industry that may provide
one at a cost. When you feel strongly about the art. Get one.
Many are done for the IRS, insurance, and resale valuations.
A letter of transmittal for art is a formal, brief, one-page cover
document that accompanies artwork, portfolios, exhibition
materials, or contracts being sent to a gallery, curator, client, or
institution.
The letter can verify a visual inspection, readily
apparent identity of the piece, provide scope of work and
attribution, but it has limited conditions because it is based on
the extraordinary assumption that the work is authentic.
Why is a Certificate of Authenticity good to have… What could happen if you do not have one…
Reduced Value: Artworks lacking proper documentation often
command lower prices at auction and during resale. But it does
not mean the artwork is not in demand, desirable or authentic.
Great opportunities present itself in these situations.
Lack of Provenance: A COA acts as a historical record, helping to
verify the work’s origin. In the primary market, it may be a sign
of a non-professional sale. But in the secondary market working
with a good curator is very helpful.
Just be aware of COA’s that lack detail, have vague
information, or come from unverified sources.
Certificates with out a without a physical location or long-standing reputation.
can bring more things into question. Working with a trusted curator or advisor helps a lot.
Therefore, even though a COA is not the only way nor always the most reliable way to prove
a work of art is genuine. A Certificate of Authenticity is a common tool for establishing trust. Remember, there is other solid and just as relevant documentation.
