How does it work and how much does it cost?

Because no two works of art are the same, the authentication process and its associated fees vary. We don’t have fixed prices, which allows us to be flexible and find a solution that works for your budget.

To get a personalized quote, please submit at least two high-resolution images (front and back) of your artwork, along with some information about its known provenance and how it was acquired, with our easy-to-use online form.

Get started

Typically within 48 hours, you’ll receive information and a proposal from one of our authentication research specialists. This proposal may include a combination of the important techniques, commonly used for art authentication.

Our Techniques

Comparative Analysis

A side-by-side comparison of your work of art to others that have been positively attributed to the artist in question. We form a professional option based on careful consideration of many factors related to the artist's documented technique and stylistic preferences.

Provenance Research

The important task of tracing your work of art all the way back to the artist who created it. We search the world’s top libraries and archives to fill in the missing pieces of your artwork’s history with records of sale and exhibition, legal documents and old photographs.

Scientific Analysis

The use of special technology to look beneath the surface of a work of art and study the materials that were used to create it. We look for attribution clues with the aid of advanced imaging, and can accurately date a work of art by testing pigment and other material samples.

What is the difference between an appraisal and authentication?

An appraisal is the estimate of an item's value. Authentication is an in-depth investigative research process used to determine whether an artwork's attribution (who made it) is accurate.

Can I have a work of art appraised online by Mearto without purchasing an authentication product?

Absolutely! In fact, we recommend that you start with a conditional valuation , so you know how much your work of art could be worth before investing time and money into the authentication process. Our specialists can determine the fair market value of your artwork (on condition of authenticity) within 48 hours for just $21.

Does Mearto need to see the artwork in person to authenticate it?

For the first two steps, comparative analysis and provenance research, we can work from photographs and the information that you provide through our online form. For the third and final step scientific analysis, an in-person physical inspection of the artwork is necessary.

Which artists does Mearto authenticate?

Mearto can authenticate any work of art from the secondary market with a minimum estimated value of $1,000 or more. We examine paintings, drawings, prints, sculptures and some works of decorative art. We have experience with hundreds of artists, from household names like Monet, Van Gogh and Picasso to the more obscure, across nearly every genre and from all over the world.
