ANTIQUES ROADSHOW is an antiques appraisal event and television production; we do not buy or sell objects, and conducting any business with an appraiser at the ANTIQUES ROADSHOW event is strictly forbidden.

If you decide to do business with an appraiser who has appeared on ANTIQUES ROADSHOW, please keep in mind these tips before consigning or selling an item:

  • Get more than one referral and check references
  • Get valuations of your item from more than once source
  • Compare options between different types of sellers, i.e., a dealer versus an auction house
  • If you are considering consigning an object for auction, be sure to inquire how the item will be priced, the size of the fee, and the expected amount of time the process may take. Find out what will happen if it doesn't sell.
  • Check the appraiser's professional associations (such as International Society of Appraisers, American Appraisers Association, National Auctioneers Association)
  • Consult an attorney before signing a contract
  • Whatever kind of transaction you decide to enter into, always get a detailed written receipt for your records
