AUBURN — What creates demand for certain antiques, and why does demand and value decline for others? Daniel Buck Soules will speak at 7 p.m. Tuesday, Oct. 23, about “Unique Antiques” at the next meeting of the Androscoggin Historical Society at the Society’s headquarters on the third floor of the County Building, 2 Turner St. 

These are not easy questions, says Soules. “The answers depend on what part of the country you’re in, and what you are buying, especially in this ever-changing market.”

The Lisbon Falls resident, who lives in an early 19th-century farmhouse, has been an antiques appraiser and auctioneer for more than 40 years. For 11 years he appeared as an independent appraiser of decorative art, silver and collectibles on the PBS television show “Antiques Roadshow.” For the past several years, Soules has lived and worked in Maine. His office is at 501 Lisbon Road (Route 196) in Lisbon.

Over the last 20 years Soules has been involved with New England museums, organizations, and historical commissions, serving on the board of directors or a committee for a number of them. Much of his work is helping clients with insurance and estate appraisals. He specializes in Americana of the 18th and 19th centuries, Shaker items, and 19th- and 20th-century paintings.

His career in the antiques business began at the age of 12 and he began auctioneering four years later. He graduated the International Auction School in Deerfield, Massachusetts, at the top of his class. He was employed by the Hancock Shaker Village in Massachusetts for about five years, serving as a cabinetmaker and interpreter, and he co-authored “Simple Gifts,” a Shaker how-to book.

Attendees should use the Court Street entrance. An elevator is available. There is no charge for attending, but donations are accepted.
