An art appraisal is not an art authentication certificate

It's a prevalent misconception in the United States that an art evaluation is the same as an art authentication. It could not be more incorrect. An art appraisal is an opinion on the fair market worth or replacement value of an object. If the artwork is a forgery or a copy, the art appraiser has no obligation.

A/ Fair market value: The price at which personal property would be sold voluntarily between a buyer and a seller. The auction value is often regarded as the fair market value.


B/ Replacement value: The amount that an entity would pay to replace an existing asset at current market value with a comparable asset. Because the replacement asset is usually located in a gallery, the replacement value is often compared to the gallery value. This gallery value is similar to the auction value, and it may be twice or treble the auction amount.


The following steps are included in the art authentication process:


Authenticity is justified by comparison with other works by the artist. Reintroduce the works to the "catalogue raisonne" Comparison to other works by the same artist from the same time period In comparison to other artists from the same era or movement Investigate the history, origin, and so forth. Restore the painting's history Handwriting graphology analysis Signature examination Painting analysis on-site Eventually, the pigments will be studied. Investigate the assistance Examine the method Wood lamp evaluation


The Presentation of the File to a Recognized Expert


Each great artist has his or her own "SOLE RECOGNIZED AUTHENTICATOR". Sotheby's, Christie's, or any other large gallery lacks the power to provide an authentication certificate for an object. Sotheby's and Christie's, as well as any other reputable auction house, will check with the artist's single certified authenticator before included it in their sale. They should, yet we now know that numerous forgeries were sold at these prominent auction houses. Art experts in general may provide an opinion at their own risk (remember, in the United States, anybody may sue anyone for any reason...), for which they may be sued if the only authenticator declines to verify an artwork. Because of the prospect of suing a person or an organization in the United States, numerous large organizations, like the Warhol-Pollock-Haring-Dekooning Foundation, opted to discontinue the authentication service. If you did not become an authentication before they chose to terminate the authentication service, there is only one alternative left for these painters: create a file that verifies the authenticity of the item with incontrovertible and verifiable justifications.
