Appraisal vs. Certificate of Authenticity
Appraisals are not certificates of authenticity; these are very different documents. An appraisal is an opinion or statement of the value rendered by a professional appraiser who acts as an independent, impartial third party. A certificate of authenticity is an opinion or statement of authenticity.
In preparing the appraisal an appraiser may rely on a certificate of authenticity as well as on third parties and/or published information, including catalogue raisonnes, exhibition catalogues, auction catalogues or other available information. Third parties might include scholars, museum curators, conservators, descendents or associates of an artist.Appraisals are done for a variety of reasons, but all are related to establishing the value of an item or a collection, often for insurance purposes, for IRS reporting or for liquidating an estate. A certificate of authenticity is done to establish the authenticity of an item or items, and the COA may be provided to the appraiser as part of the appraisal process.
