Why Certificates of Authenticity do not Protect YOU! part 1

The day a collector acquires a certificate of authenticity is often the day they stop asking questions.
That is understandable. A certificate feels reassuring. It has a letterhead. It bears a signature. It may include photographs, descriptions, dimensions, and even official-looking seals. To many buyers, a certificate appears to represent certainty.
In reality, a certificate often represents nothing more than an opinion.
During more than four decades in the art world, I have encountered collectors who spent thousands, hundreds of thousands, and in some cases millions of dollars relying on certificates that later proved to be worthless. Some certificates were issued by individuals with little expertise. Others were issued by respected experts whose opinions were later challenged. A surprising number were simply fabricated.
The uncomfortable truth is that a certificate does not make a work authentic. It merely records that someone believed it was authentic at a particular moment in time.
That distinction can be extremely expensive.
The Illusion of Security
Most collectors assume that a certificate is a form of protection.
After all, when purchasing jewelry, a diamond certificate provides a measurable description of the stone. When purchasing a vehicle, title documents establish ownership. When purchasing real estate, deeds and records have legal standing.
Many buyers assume that certificates in the art world function in a similar manner.
They do not.
Art authentication remains one of the few fields where reasonable experts can examine the same object and reach completely different conclusions.
A certificate does not eliminate uncertainty. In many cases, it merely disguises it.
I have reviewed works accompanied by impressive folders containing certificates, letters, invoices, photographs, appraisals, and supporting documentation. At first glance, everything appeared convincing. Yet after careful examination, significant problems emerged.
The certificate was real.
The artwork was the problem.
Who Issued the Certificate?
One of the first questions I ask is surprisingly simple:
Who signed the certificate?
Many collectors never investigate this point.
The art market contains certificates issued by:
Independent experts
Former gallery owners
Family members of artists
Foundations
Scholars
Dealers
Auction houses
Individuals with no recognized expertise whatsoever
The value of a certificate depends almost entirely on the credibility of the person or organization issuing it.
A certificate signed by an unknown individual may carry little weight with a museum, auction house, insurer, or major collector.
Even certificates issued by respected authorities can lose influence when scholarship evolves.
Art history is not static. Opinions change. New evidence emerges. Archives are discovered. Scientific testing improves. Scholars disagree.
What was accepted twenty years ago may be questioned today.
