What a certificate of authenticity is, and what it is not

What a certificate actually is

A statement by the maker, in writing, that a particular object is the work it claims to be and that they made it.

That is the whole thing. It is a document, and its function is to travel with the work so that the next person to ask “what is this and where did it come from” has an answer that does not depend on memory.

There is no register, no authority, no body that issues them. No institution verifies a certificate, no number is checked against anything, and no law requires one to exist. Anyone with a printer can produce a document with the words certificate of authenticity at the top, and quite a lot of people do.

That sounds like it should make certificates worthless, and it does not — for the same reason that a signature on a letter is not worthless even though anyone can hold a pen. It is worth what the signer is worth. The paper is not the evidence; the person is.

What belongs on one

A useful certificate is specific enough to identify one object and nothing else. Anything less is decoration.

For an edition, the size is the point. A certificate that says “limited edition” without saying how large that edition is, and when the size was fixed, is not describing a limit. A number on a sheet does not describe one either — a run of five hundred can be numbered too. What makes a limit is that the quantity was settled before the first sale and the run is never reopened. Editions here are capped at fifty per painting, printed once and never reprinted — what that promise commits to is in why a closed edition is never reprinted.

What is not needed: a photograph of the work, an embossed seal, a hologram, a QR code, or a wax stamp. None of those is evidence of anything. They are design choices, and the more of them a certificate carries, the more it is working to look like proof.

Four things it is not

Not a valuation. A certificate says what a thing is, never what it is worth. Any certificate carrying a price or an estimated value is doing something other than documentation, and what it is doing is selling.

Not an independent verification. Nobody checked. The maker asserts; the certificate records the assertion. That is legitimate and it is also all it is.

Not a guarantee of future value. No document can promise that, and a seller who implies it is telling you something they cannot know. The longer version of that argument is does erotic art hold its value?

Not a substitute for looking at the object. This is the one that actually costs people money. Paper is easy to print; a painted surface is not. Everything in is it really hand-painted? is better evidence than a certificate, because it is evidence about the thing itself rather than about a claim.

The order to hold these in: the object first, the maker second, the paper third.

When it is actually worth something

Three moments, and they are the reason to keep it somewhere you will find it again.

Insurance. A household policy covering an individual item usually wants a description and a value. The certificate supplies the description; the invoice supplies the value. Together they are the ordinary answer to “what is it and what did it cost”.

An eventual sale. Provenance is the record of who has owned a work, and buying direct makes it as short as it can be: painter to first owner. The certificate is where that chain starts, and a chain with no gaps is worth more than the paper it is written on. What else changes when there is no intermediary is buying art direct from the artist.

Inheritance. The person who eventually finds a canvas in a house did not watch you buy it. The certificate is the difference between “a painting” and “this painting, by this painter, bought new”.

In all three the pattern is the same: the certificate answers the question how do you know this object is the one described, at a moment when the person asking was not there.

What matters more than the paper

If you are trying to decide whether a work is what it claims to be, this is the order that actually works.

1. The object. Paint over the side of the stretcher, brush direction that catches the light unevenly, thick paint casting its own small shadows, a signature that sits in the paint rather than on it. Six checks, all visible in a photograph, all harder to fake than a document.

2. The maker. A name, a place, a body of work, and someone who answers email. Willem van der Krieken paints in Boekel, Noord-Brabant. A studio you can ask a question is worth more than any certificate that studio could print.

3. The listing. “Original”, “print”, “edition” and “reproduction” used precisely, with the edition size stated where there is one. A seller careless with those words is telling you something.

4. Then the certificate. Which now means something, because there is a person behind it.

What ships with an original here. The work is signed, and a certificate of authenticity comes in the box, recording what it is and that it exists once. That is normal practice rather than a feature — and it is worth saying so, because a studio that presents a receipt as a guarantee is overselling.

What the certificate is describing has a page of its own: what an original oil painting is.

• The twenty-three originals — oil on canvas, one of each, signed and documented.
• What arrives, and in what — the whole route from order to hook.

Questions people ask

What does a certificate of authenticity actually prove?

That the maker says this object is the work described and that they made it. It is documentation rather than verification: no authority issues certificates, nobody checks them, and no law requires one. Its value is the value of whoever signed it — from a contactable painter with a real body of work it means something, from an anonymous shopfront it does not.

What should be on a certificate of authenticity?

The title, the medium and support, the exact dimensions, a statement that it is one of one or the number and size of the edition, the maker’s name and place, and a signature by hand. What is not needed is a hologram, an embossed seal or a QR code — those are design choices, not evidence.

Does a certificate of authenticity increase a painting’s value?

No. A certificate records what a work is; it says nothing about what it is worth, and any certificate carrying a valuation is doing something other than documentation. What it does do is make the work easier to insure, sell or pass on, because it answers how you know this object is the one described.

Can a certificate of authenticity be faked?

Easily, which is why it should never be the first thing you rely on. Paper is simple to print; a painted surface is not. Look at the object first — paint over the stretcher edge, brush direction, raised paint casting shadows — then at whether there is a real maker with an address, and only then at the certificate.

Do the paintings from this studio come with a certificate?

Yes. Every original is signed and ships with a certificate of authenticity recording what it is and that it exists once. That is ordinary practice for selling an original rather than a distinguishing feature, and it is worth exactly as much as the studio behind it.
