Studies have explored the economics surrounding the emergence of superstars, but relatively little research exists on the associated memorabilia markets. Using a sample of autographed artifacts, on sale through an internet outlet, hedonic analysis is used to gain insight into the significant characteristics of price determination. The data consists of current and former autographs of National Basketball Association (NBA) players on photographs. This study explores price differences with respect to a number of independent variables related to the artifact and player status. A notable difference emerges among framed and limited edition pieces, and pieces signed by top-ranked players.
