How to Estimate the Value of a Painting?
Who Can Reliably Appraise a Painting?
Why Have a Painting Appraised? Have you inherited an old painting, found a work during a house clearance, or are simply wondering about the value of a signed artwork? Having a painting appraised is the first essential step before any sale, inheritance, donation, or insurance coverage. An appraisal allows you to: - understand the artwork’s current market value; - avoid pricing mistakes if you intend to sell; - protect the piece with appropriate insurance; - prepare a fair and informed succession or donation process. But for this, you must consult a qualified expert — someone capable of assessing all key criteria: provenance, signature, condition, period, rarity, and the artist’s market standing.
Not all paintings have the same value — even if they are old or signed.
To obtain an accurate estimate, it is essential to consult a qualified fine art professional.
In Marseille, Galerie Alexis Pentcheff has been supporting private individuals, families, notaries, and collectors for over 15 years. The gallery is recognized for its expertise in 19th- and 20th-century paintings.
Alexis Pentcheff is a CNES-certified expert, specializing in French schools, particularly Provençal, Post-Impressionist, and Modern art.
What Are the Key Criteria for Appraising a Painting?
An expert bases their appraisal on several complementary criteria:
The artist
A signed work, or one correctly attributed to a known artist, generally holds greater value. Certain names — such as Albert Marquet, Henri Martin, or Maurice Denis — are especially sought after.
The subject, size, and technique
A large, luminous seascape in oil on canvas will not carry the same value as a small, dark landscape on panel. The subject matters: views of Marseille, calanques, portraits, or Orientalist scenes are particularly appreciated.
Provenance and exhibitions
A painting that belonged to a notable collection or was exhibited in a major gallery or retrospective gains in credibility — and in value.
Condition
A painting in its original state, with no major restorations or overpainting, is often more desirable. The expert will assess the paint layers, varnishes, potential flaking, and general structural condition.
Comparable auction results
A reliable expert draws on recent auction sales and their experience of the current art market to define a realistic value range.
Is a painting appraisal is free?
Some appraisals can be free of charge, especially if the artwork is intended for sale through the gallery. For more complex requests (inheritance, insurance, inventory), a formal written certificate or expert report can be provided — with a fee depending on the scope of the service.
At Galerie Alexis Pentcheff, we offer:
- free preliminary appraisals based on photographs;
- official valuation certificates by appointment or on-site (quote upon request);
- full support for sales, donations, inheritance planning or insurance purposes.
