The authentication board dissolved in 2012, so the catalogue raisonné and provenance now carry the whole argument.
Pittsburgh5 weighted checks
The single most important fact about the Warhol market is that nobody authenticates Warhols any more. The Andy Warhol Art Authentication Board dissolved in 2012 after years of litigation, and no successor body issues opinions. Anyone offering to authenticate a Warhol is selling an opinion the market does not have to accept.
What exists instead is documentation. The prints are recorded in the standard catalogue raisonné compiled by Feldman and Schellmann, which states editions, publishers, printers and markings for each image. A print that matches its catalogue entry in every respect has the strongest case available.
Warhol's own practice complicates signatures. He signed some prints in pencil, some in ballpoint, some with a stamp, and the Estate applied stamps to works after his death. A stamped signature is not a forgery — it is a documented practice — but which marking belongs to which edition is precisely what the catalogue records.
The Feldman and Schellmann catalogue raisonné of Warhol's prints is the reference the market uses. For each image it states the edition size, the year, the publisher, the printer, the paper, and how the edition was signed and numbered. Matching a print against its entry is the core of the argument.
Signatures vary by edition and are not interchangeable. Pencil, ballpoint and stamped signatures all appear on genuine work, and some editions were signed on the verso rather than the recto. A pencil signature on an edition the catalogue records as stamped is a problem; so is a stamp on an edition recorded as pencil-signed.
After Warhol's death, the Estate and the Foundation applied stamps to works from the studio inventory. Those stamps are documented and legitimate, and they describe a work's status rather than certifying it.
The Authentication Board's dissolution in 2012 means no body issues opinions today. Provenance, catalogue matching and scientific analysis are what remain.
Ordered by how much each one settles. The decisive checks are the ones worth your first five minutes; the supporting ones only matter once those are clean.
Edition size, year, publisher, printer, paper, dimensions and signing convention should all agree with the Feldman and Schellmann entry for that image. A discrepancy in any one of them is where the case starts to fail, and edition size is the commonest.
Pencil, ballpoint and stamped signatures all appear on genuine Warhols, and the catalogue records which belongs to which edition. A signature of the wrong type is a strong signal — it means the forger worked from a general impression of Warhol rather than from the record.
Warhol's prints are screenprints: flat opaque ink in registered layers, with slightly raised edges where colours meet and no dot pattern. An inkjet or offset reproduction shows a rosette or a fine grid. This separates prints from posters immediately, and a great deal of what people bring is posters.
The catalogue states the paper and the sheet dimensions. Measure. Trimmed sheets, wrong paper stock, or an edition fraction written in a hand inconsistent with the run are all failures.
With no authentication board, provenance carries weight it would not otherwise. Gallery invoices, exhibition history, prior auction records and an unbroken ownership chain are the substitute for a certificate, and they are what a serious buyer will ask for.
The Warhol market has two problems and only one is forgery. Fakes exist in quantity, particularly of the most reproduced images, and are usually caught by the loupe and the catalogue.
The larger problem is that the dissolution of the Authentication Board left a vacuum, and into it came a great many private opinions and impressive-looking certificates from bodies with no standing. A certificate for a Warhol is worth exactly as much as the issuer's reputation, which for most issuers is nothing.
Each of these is checked differently. The ones with their own page have enough that is specific to them to be worth reading separately.
Several editions across years, each with its own catalogue entry.

Read within the checks aboveAuthenticity and value are separate questions, and answering the first is usually a step towards the second. These are broad ranges for honest, unrestored condition — an orientation, never an appraisal.
| Category | Market behaviour | What moves it most |
|---|---|---|
| Catalogued prints with strong provenance | Strong and liquid | Image, edition, condition |
| Catalogued prints, thin provenance | Discounted | How far the paper trail goes back |
| Estate-stamped works | Distinct category | Documentation of the stamp |
| Uncatalogued works | Very difficult | No authenticator exists to resolve them |
Since 2012 there is no authentication board. Provenance does the work a certificate would elsewhere.
