Appraisals and Authentications

As a non-profit institution, the Addison Gallery is prohibited from providing appraisals. Nor do we provide authentications. If you are looking for a monetary evaluation of an object for insurance or other purposes, contact a professional appraiser in your area. Many auction houses and independent antiques dealers offer appraisal services. Member associations such as those listed below can also refer you to specialists by region:
