Resources of Heritage Auctions Appraisal Services
AuthenticationThough our experts perform their due diligence when appraising a piece, an appraisal report is not proof of authenticity. There are, however, other organizations that can assist in authenticating your art and collectibles. Please contact the Appraisal Services specialists to discuss the best authentication process for your valuable.
