Is My Painting Valuable? How to Assess Old Paintings
Find out if an old painting is valuable: original vs. print, signature, canvas and stretcher clues, labels, condition and when to consult an art specialist.

An old painting in a gilded frame looks impressive — but is it an original oil, a decorative copy or a print? Here's how to start assessing it before you hang, sell or toss it.
1. Original or print?
- Brushstrokes: originals show raised paint texture, especially in oils. Tilt the painting under a light.
- Magnifier: prints often show tiny dots in a regular pattern.
- Edges: paint on originals often stops irregularly at the canvas edges.
- Overpainted prints: some reproductions have brushed varnish on top to mimic texture — look closely.

2. Look at the back
The back often reveals more than the front:
- Canvas: hand-woven, aged linen vs. modern machine canvas
- Stretcher: older keyed wooden stretchers vs. modern staples
- Labels: gallery, exhibition, framer, auction labels
- Inscriptions: titles, artist names, addresses
3. The signature
Signatures help, but they're easy to add. Check that the signature sits within the paint layers (not on top of varnish), and research the artist. Many good paintings are unsigned.
4. Subject and style
Period style, subject and technique suggest an era and region. Some subjects are more popular with buyers.
5. Condition
Flaking, tears, heavy discolored varnish and overpainting affect value. Don't clean a painting yourself — solvents can remove paint. Leave that to a conservator.
6. The frame
Antique frames can be valuable in their own right, sometimes more than the painting.
When to call a specialist
If the painting seems original, has labels or a recognizable signature, or just feels "right", contact an auction house's paintings department or an appraiser. See how to find an antique appraiser.
First step: scan it
Scan the painting with AntiqueIQ for an identification, estimated era and value range, and photograph the back and signature for research.
