How Much Is My Painting Worth?
Maybe it came from a flea market, an inheritance, or it has simply hung on the wall for decades. Whatever the story, the question is the same: is this painting worth $50 or $50,000? Here is how value is actually determined — and how to get a serious, evidence-based estimate without shipping the work to an auction house.
The six factors that determine a painting's value
- The artist. Attribution is the single biggest driver. A work by a “listed” artist — one with a documented auction record — has a market reference point; an anonymous work is valued mostly on decorative merit.
- Authenticity. An original oil, a hand-signed print, and a photomechanical reproduction of the same image can differ in value by several orders of magnitude.
- Medium and size. Oils generally command more than works on paper by the same artist, and larger, exhibition-scale works usually more than small studies.
- Condition. Tears, overpainting, discolored varnish, and water damage all reduce value; sensitive restoration can preserve it.
- Provenance. A documented ownership history — gallery labels, receipts, exhibition stickers — supports both authenticity and price.
- Comparable sales. Ultimately, a painting is worth what similar paintings by the same artist have recently sold for at auction and in galleries.
Step 1: identify the artist
Check the lower corners of the front for a signature or monogram, then examine the back: canvas stamps, stretcher inscriptions, gallery and exhibition labels, and auction lot stickers are often more informative than the signature itself. If the signature is hard to read, our guide to identifying an artist's signature walks through deciphering it.
Step 2: find comparable sales
Once you have a likely artist, the market record tells the story: realized auction prices for works of similar size, medium, period, and subject. Realized prices matter far more than asking prices — a gallery can ask anything, but an auction hammer price is what a buyer actually paid.
Step 3: get an estimate — instantly, from a photo
ArtVal does all of the above from a single photograph. Snap the painting, and in about a minute you get the likely artist and title, an art-historical dossier, an estimated value range with a confidence level, and the comparable sales the estimate rests on. See exactly what that looks like in our sample appraisal report.
When you need a certified appraisal
AI estimates are informational. For insurance scheduling, estate tax, charitable donation, or litigation you will need a certified appraiser's written report — but arriving with the artist identified and a realistic value range saves time and money, and tells you whether the formal appraisal is worth commissioning at all.
Common questions
How much is my painting worth?
A painting's value depends on who made it, its authenticity, size, medium, condition, provenance, and what comparable works have actually sold for. Signed works by listed artists can be worth thousands; decorative unsigned paintings often sell for under a few hundred dollars. The fastest way to get an evidence-based estimate is a photo-based AI appraisal that checks auction records and comparable sales.
How can I find out who painted my painting?
Start with the signature (front lower corners, or the back of the canvas and frame), then labels, stamps, inscriptions, and gallery stickers on the reverse. Image-recognition tools can match the style and signature against known artists — ArtVal does this automatically from a photo.
Is there an app that tells you what a painting is worth?
Yes. ArtVal identifies a painting from a photo, researches the artist and comparable auction sales, and returns an estimated value range with a confidence level in about a minute. AI estimates are informational and not a substitute for a certified appraisal for insurance or legal purposes.
Are old paintings always valuable?
No. Age alone rarely determines value — attribution, quality, subject, condition, and market demand matter far more. A 19th-century unsigned copy may be worth less than a contemporary work by a sought-after artist.
