The Collecting Channel will host a live chat with David Maloney, its Chief Appraisal Officer and author of "Maloneys Antiques & Collectibles Resource Directory." David will answer such questions as "What is an appraiser?" "Why use an appraiser?" "How does one become an appraiser?" "How valid are online appraisals?" and more. He'll also be giving away an autographed copy of the new 6th edition of his book. http://www.collectingchannel.com - Wednesday, August 29th at 9pm EST.
