Contact a local art gallery or art association, like the American Society of Appraisers, to find a reputable art appraiser in your city. Find an art appraiser with expertise in the style of the piece of artwork you would like to have appraised.
Arrange an appointment with the art appraiser. Depending on the art appraiser's experience and expertise, you may need to set up an appointment far in advance. Be prepared to bring the artwork to the appraiser, and inform the appraiser if it is difficult to move the artwork.
Pay any fees to appraise the artwork. Some appraisers charge a fee for their services, so it is best to ask ahead of time whether a fee is required. If you are unwilling to pay a fee, call multiple art appraisers to shop around for the best deal.
Obtain a certificate or other written instrument that includes the name of the appraiser and the appraiser's estimated value of your artwork. The writing should include a description of the artwork, including the artwork's condition and size. In addition, the writing should provide the appraiser's contact information and the appraiser's signature.
