What drives the value of a work by Jean-Michel Basquiat

Large acrylic and oilstick paintings — Unique paintings on canvas or on assembled wood supports from the early to mid-1980s, often combining acrylic, oilstick, spray paint and collaged photocopies, form the top of the market and are the works that international auction houses compete for. Their value depends heavily on date, scale and whether the work carries the recognisable vocabulary of crowns, skulls, anatomical diagrams and crossed-out words.

Unique drawings and works on paper — Oilstick, crayon and mixed-media drawings on paper, including notebook pages and pieces made on found paper, circulate far more frequently than paintings and are actively traded. Fully worked, signed or densely inscribed sheets are treated very differently from slight sketches or fragments.

Collaborations and painted objects — Works made jointly with Andy Warhol, painted doors, refrigerators, helmets, furniture and other found objects from the studio are scarce and attract specialist interest. The market examines them closely because condition, documentation and exhibition history weigh more than usual on these hybrid supports.

Lifetime prints and editions — The artist produced relatively few editioned prints during his lifetime, mainly screenprints, and these are valued but remain a secondary segment compared with unique works. Signed and numbered impressions in good condition are the only ones the trade treats as genuine collectable editions.

Posthumous editions and licensed items — Estate-authorised prints, and above all licensed products such as skateboard decks, textiles, toys and reproduction posters issued long after the artist's death, form a decorative and design market. They are bought as merchandise or design objects, not as original works, and are valued accordingly.

Basquiat rarely signed in the conventional manner on the front of paintings: he more often inscribed his SAMO© tag in his earliest street and postcard period, or embedded his name, initials, a crown, dates and copyright symbols within the composition itself as part of the imagery. Many canvases carry a signature, title or date on the reverse, on the stretcher or on the wooden support, sometimes in oilstick or marker; drawings may be unsigned altogether. Since his death, opinions on authenticity have been handled by his estate, and works normally rely on documented provenance, exhibition history and inclusion in published catalogues rather than on a signature alone; owners should note that the authentication committee once associated with the estate no longer issues opinions.

• Offset lithographic reproductions and exhibition posters printed for museum and gallery shows are routinely mistaken for prints, but under magnification they show a regular dot matrix and flat, even ink instead of the ridged, waxy build-up of oilstick or the thick deposit of screenprinted ink.
• Posthumous and licensed reproductions, including estate-stamped or foundation-approved editions, are often presented as 'original prints' although they were not printed under the artist's supervision and must be described as posthumous.
• Crude fakes are common because the vocabulary is easy to imitate: they typically show hesitant, evenly pressed crowns and lettering, uniform modern acrylic paint, artificially aged paper and an unusually neat signature with a date on the front.
• Works on paper torn from books, photocopies of drawings that the artist himself used as collage material, and later photocopied sheets are frequently sold as unique drawings, and only close inspection of the surface and paper reveals the absence of any hand-drawn medium.

• Paintings from the peak mid-1980s years and from the immediately preceding period, when the heads, crowns, skeletal figures and word lists are most fully developed, are placed well above late works and above slight or transitional pieces.
• Recurrent motifs that the market identifies with the artist, notably the three-pointed crown, the skull or head, boxers, jazz musicians and griot figures, are preferred to purely abstract or sparsely worked compositions.
• Provenance through the galleries that showed him in his lifetime, early exhibition catalogues, and an unbroken chain of ownership are decisive, since the absence of an authentication body makes documentation the main guarantee.
• Condition problems are medium-specific and costly: oilstick and crayon smudge and transfer, unvarnished acrylic on raw wood or canvas is vulnerable to abrasion and staining, collaged photocopy elements yellow, and works on paper fade, cockle and tear at the edges.

• Photograph the entire front in even light plus close-ups of any crown, inscription, date, copyright symbol or signature, with a raking-light shot showing whether the marks sit in relief or lie flat in the paper.
• Photograph the complete reverse, including the stretcher bars, any wooden slats, inscriptions, numbers, gallery or shipper labels, customs marks and framer stickers, without removing anything.
• Record the support itself: sheet or canvas dimensions, watermarks or paper type, any edition number and printer or publisher blindstamp, and any estate or studio stamp, along with all invoices, certificates, catalogues and family documents you hold.
