Study of Ebay Auction Techniques Documented in New York Times
Sunday's New York Times contained an article about a study of eBay coin pricing by Charles Wood and Robert Kauffman. This article summarizes the results of a two year study of auctions of 19th century coins, and best practices for sellers that will result in maximized sale prices.
Art Iger from J.P. Morgan Chase pointed this study out in his Technology Industry Daily newsletter at least a month ago, but it looks like CTDATA never published a link to it. Belated credit to him.
