How Much Is an Old Oil Painting Worth?
Found an old oil painting in an attic, an estate or a thrift store? The first thing most people do is look up a similar painting for sale, see a big number, and get excited. The catch: asking prices for paintings are often many times what paintings like them actually sell for. Value depends on who painted it, quality, subject, size, age and condition, and on what buyers have really paid.
What real numbers show
Three real examples from recent price checks (October 2026):
- Victorian-era portrait, signed "Nadine", oil on canvas in an ornate frame: one was listed at $2,300, while similar portraits sold for a median of about $75 across 17 sales. See the price check.
- Portrait of a woman in a pink jacket, by Stefani Kosik: listed at $1,630; comparable paintings sold for a median of about $35 across 30 sales. See the price check.
- Harold Hayden 12x18 oil on canvas, abstract figurative: comparable paintings were listed at $300 to $349. There weren't enough sales to say what they actually sell for. See the price check.
The lesson: a painting is worth what a buyer pays, and for most decorative and lesser-known artists' work that is far below the asking prices you see online.
What drives value
The artist. A recognized artist with an auction record is the biggest factor. Look for a signature, then check whether that artist has sold results. Quality and subject. Skilled work and sought-after subjects sell better. Original vs. print. Check for brush strokes and raised paint; many "paintings" are prints or decorator pieces. Condition and frame. Tears, flaking paint and heavy grime lower value, while a good period frame can add to it. Age and provenance. Documented history helps.
How to price yours
Photograph the front, back and signature. Look up sold results for the artist (not current listings). If the artist has a real auction record, or the painting looks old and skilled, get a professional appraisal. See what an antique appraisal costs.
Frequently asked questions
Is a signed painting always valuable?
No. A signature only matters if the artist has a market. Many signed paintings are by hobbyists or decorative studios and sell for modest sums.
Why are online prices so high?
Sellers can ask anything. What matters is what similar paintings actually sold for, which is often a small fraction of the asking price.
