Here's the brutal truth about paintings: most of what people think they own is worth very little, but occasionally someone finds a masterpiece in the attic. I've seen $50 garage sale paintings turn out to be $500,000 surprises. The painting market ranges from $200 regional landscapes to Leonardo's $450 million record sale. The key question isn't whether it's old - it's whether the right name is in that bottom corner.
Attribution is everything, and the art world has a cruel hierarchy. "By Monet" means millions. "Attributed to Monet" means maybe hundreds of thousands. "In the style of Monet" means you have a nice painting worth maybe $5,000. Each step down that ladder costs you 80-90% of the value. Don't let auction houses fool you with fancy language - "after" and "follower of" are polite ways of saying "not by."
Here's what drives me crazy about painting condition: people think they're helping by cleaning them. That dark, "dirty" varnish? It might be original and intentional. Over-cleaning destroys original glazes forever - I've seen million-dollar paintings ruined by well-meaning "restoration." If it's been in your family for decades, photograph it as-is. Professional conservators can work miracles, but only with original material to work with.
Types of Antique Paintings We Value

Price Ranges by Style & Period
Verified hammer prices from Sotheby's, Christie's, Bonhams & Heritage Auctions. Maker attribution and provenance can push individual pieces well above these ranges.
| Style | Period | Typical Range | Key Value Driver |
|---|---|---|---|
| Old Masters | 1400-1750 | $1,000 - $100M+ | Attribution is everything; documented panel paintings with provenance to important collections lead the market |
| 18th Century European | 1700-1800 | $500 - $5M+ | Grand Tour portraits, Dutch genre, Italian vedute; signed and documented works command multiples over attributed ones |
| Barbizon School | 1830-1870 | $1,000 - $500,000 | Corot, Millet, Daubigny; original plein-air sketches vs. finished studio works trade differently |
| Hudson River School | 1825-1875 | $2,000 - $2M+ | Church, Bierstadt, Kensett; large finished exhibition pieces vs. small oil sketches; demand remains strong |
| American Impressionist | 1890-1930 | $2,000 - $2M+ | Hassam, Sargent, Tarbell; signed, dated, documented works lead; unsigned works typically 10-20% of signed equivalents |
| British Victorian | 1837-1901 | $500 - $500,000+ | Pre-Raphaelites and narrative painters (Alma-Tadema) lead; genre scenes and sporting paintings actively traded |
| Early American | 1750-1850 | $500 - $200,000+ | Portraits and still lifes; documented attribution by Peale, Stuart, or Copley extremely valuable |
| Modern (listed artists) | 1900-1960 | $200 - $5M+ | Signed, exhibited, and provenance-documented works by listed artists with gallery records command the most |
Condition, provenance, and documented maker attribution significantly affect realized prices.
What Affects Antique Paintings Value?
These six factors account for the majority of price variation at auction. Understanding them before you sell — or buy — can make a substantial difference.
See a clear signature that matches known examples? You might have won the lottery. No signature or a questionable one? You've lost 80-90% of potential value right there. Signatures can be faked, added later, or painted over. I've seen people spend thousands authenticating signatures only to find out they were added by a hopeful relative in the 1960s.
Museum exhibition labels, old gallery stickers, auction house stamps on the back - this is gold. A painting that was exhibited at the Met or Whitney has instant credibility. Previous auction records show you exactly what it sold for and when. Family stories are nice, but documentation is what counts at serious auctions.
I see this disaster constantly. Original condition with natural aging beats "restored" every time. That dark varnish might be original. Those little losses? Part of the character. Heavy restoration shows up instantly under UV light and kills collector interest. If you must restore, use a real conservator, not your local picture framer.
Pretty girls sell better than old men. Sunny gardens beat gloomy interiors. Dogs and children are always popular. Nudes can be tricky depending on the venue. For American artists, American scenes usually outperform European ones. It's shallow, but it's the market.
Museum-size paintings were meant to impress and often do. But really huge paintings can be hard to hang and limit your buyer pool. Sweet spot for most collectors is large enough to make a statement, small enough to fit in a normal house. Those tiny oil sketches by famous artists? They trade surprisingly well.
Original period frames are nice and add value, but don't let a bad frame stop you from buying a great painting. You can always reframe. But if the artist chose the frame (documented), don't touch it. Some frames are worth serious money on their own - carved and gilded period frames can be worth thousands.
