Painting Value Checker

Painting value depends first on what the piece is: an original painting, a print, or a print dressed up to look like a painting. That single answer moves the price more than anything else. After that come the artist, the subject, the size, the condition and the paper trail on the back.

What drives a painting's value

• Original or reproduction. Prints of famous paintings were made by the million. Most sell for little more than the frame.
• The artist. A painting by an artist with an auction record and steady collector demand is a different item from one by a skilled amateur, even when the two look equally good.
• Subject. Within one artist's work, some subjects sell better than others. Landscapes, harbor scenes and appealing portraits tend to outsell dark still lifes and portraits of unknown sitters.
• Medium and size. Oil on canvas or board usually ranks above watercolor, and watercolor above a sketch, though this varies by artist.
• Condition. Tears, paint loss and heavy restoration lower value. Light, even wear on an old painting is expected.
• Provenance. A documented ownership history, exhibition labels or a past auction record add confidence and money.

Original or print: how to tell

Take the painting into good light and use a magnifier or your phone's zoom.

• Texture. Tilt it under a lamp. Oil and acrylic paintings show raised paint, strokes that start and stop, and ridges at the edges of strokes. A flat, even surface points to a print.
• Dot pattern. Many printed reproductions are built from tiny dots in a regular rosette pattern. A painted area shows continuous color under magnification.
• Giclée prints. These high-quality inkjet prints can look close to a painting. Up close you often see a fine, random spray of ink dots and no raised paint. Many are sold honestly as editions, so look for an edition number.
• Canvas transfers. A paper print bonded to canvas and stretched like a painting. The weave shows through, but the image sits flat.
• Added brush texture. Some decorative prints get a clear gel brushed over them to imitate paint. The strokes do not follow the shapes in the picture, and the color under them is flat.
• Edges. A painted canvas often shows drips, pencil lines or uneven color where it wraps around the stretcher. A print usually ends in a clean printed border or a plain white edge.

How to read signatures and labels

The signature

A signature tells you less than people hope. Prints reproduce the signature along with everything else, and names can be added to unsigned paintings later. Plenty of good paintings were never signed. Check whether the signature sits in the paint layer or on top of the varnish, and whether the age cracks run through it the same way they run through the paint around it. A name alone, without matching style, materials and history, proves very little.

The back of the canvas

The back is often more useful than the front. Look for:

• Gallery, framer and exhibition labels, which can name the artist, title and date.
• Auction lot numbers, chalk marks and stencil numbers from past sales.
• Canvas maker or art supplier stamps, which help date the canvas.
• Handwritten titles, addresses or inscriptions.
• The stretcher: older stretchers often have small wooden wedges (keys) in the corners, and wear and color that match the canvas.

Photograph every label, and do not remove any of them.

The frame

A hand-carved or gilded antique frame can be worth more than the painting inside it. Look for real gold leaf with red or yellow clay showing at worn edges, carved wood rather than cast plaster, and old hardware. Keep the frame with the painting when you ask for an estimate. Our furniture guide covers dating old wood and hardware.

Condition problems to look for

• Craquelure. A network of fine cracks in old paint is normal with age. Lifting or flaking paint is the real problem.
• Tears, holes and dents in the canvas, and bulges where it was pushed from behind.
• Restoration. Under ultraviolet light, retouched areas often show up as dark patches. Some restoration is normal on old paintings; heavy repainting lowers value.
• Grime and yellowed varnish, which a conservator can often clean.
• Water stains and foxing (brown spots) on works on paper.

Price guidance: decorative or collectible

We do not publish dollar bands for paintings, because prices swing too widely by artist to be useful as a general table. What holds across the market is the order of things:

• Framed prints and posters of famous paintings usually sell for the value of the frame, often a small amount.
• Canvas transfers and texture-added prints sit only slightly higher, since buyers see them as decor.
• Decorative originals (hotel art, bulk-produced oils, studio copies and hobby paintings) are real paintings, but buyers pay for how they look on a wall, not for the name. Most paintings found at home fall here, with modest value.
• Signed, numbered edition prints by artists with a following can bring more than decorative originals.
• Originals by artists with an auction record are priced artist by artist, and this is the group where real money and real mistakes happen.

The best evidence is sold results for the same artist, in a similar size, medium and subject. Asking prices on marketplaces run higher than what pieces sell for. For how photo estimates are put together, see how we estimate.

Photo tips for paintings

• Shoot the whole front straight on, frame included, in daylight without flash.
• Take a close-up of the signature, sharp enough to read each letter.
• Add one raking-light shot, with light from the side, to show brush texture or the lack of it.
• Photograph the whole back, then each label, stamp and inscription on its own.
• Measure the image area, not just the frame, and note it.

When to get a professional appraisal

If the painting looks original, carries a signature that matches a known artist, or has gallery or auction labels, get a qualified opinion before you sell. For selling, many auction houses let you submit photos for a paintings specialist to review. For insurance, estate or donation purposes, use a credentialed appraiser who follows USPAP (the Uniform Standards of Professional Appraisal Practice). The American Society of Appraisers, the Appraisers Association of America and the International Society of Appraisers all list members by specialty.

Donations have formal rules. The IRS requires a qualified appraisal for donated property valued over $5,000, and for art appraised at $20,000 or more the appraisal must be attached to Form 8283 (IRS Publication 561, checked November 2026). A photo estimate is a good first filter; it is not a formal appraisal. If the same estate holds porcelain or silver, see our collecting guides.

Questions people ask

How much is my painting worth if I don't know the artist?

Usually a modest amount, priced as decor. Still, check the back for labels before deciding.

How can I tell if my painting is an original?

Look for raised paint and brush strokes under angled light, and check with a magnifier for a printed dot pattern. Paint on the canvas edges and an old keyed stretcher are good signs.

Is a signed painting worth more?

Only if the signature belongs to an artist with a market and the painting matches that artist's work. Signatures are easy to copy and are printed on reproductions too.

Are old oil paintings valuable?

Some are, many are not. Age helps less than the artist, quality, subject and condition. Plenty of century-old paintings sell for modest amounts.

Should I clean my painting before selling?

No. Household cleaners can strip paint and varnish. Leave cleaning to a trained conservator, and only if a specialist says it is worth doing.
