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.

Scientific Analysis

FAQs

Authentication

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.
