John has maintained a lifelong interest in fine jewelry with a particular expertise in antique and period pieces. His love of antiques began in the flea markets, tag sales, and antiques shops of his native Westchester County, New York, appreciating the beauty and simplicity of 18th century English silver. While studying at Boston University, John explored his interest in the auction world by joining Skinner’s Boston gallery team part time in 2002. In 2005, John became a specialist in the Fine Jewelry Department under the close tutelage of Gloria Lieberman.

Currently, John appraises and catalogs much of the jewelry that comes into the gallery. In 2010, John joined the ranks of Skinner’s auctioneers and can be seen regularly on the auction podium, and in 2013, John became an appraiser on Antiques Roadshow.

John holds a bachelor of fine arts degree in art history from Boston University and is also a Graduate Gemologist, having received his training from the Gemological Institute of America in New York.

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

ANTIQUES ROADSHOW’s pool of experts are professionals with a wide range of experience in the antiques, fine art and collectibles community, and they are from a diverse background of auctioneers, dealers and appraisers.

All ROADSHOW appraisers are independent volunteers who donate their time and expertise to PBS and who pay their own expenses to be on the show. All business transactions are independent from ANTIQUES ROADSHOW.
