After years of owning an art gallery, Kevin Callahan and Bonnie Lindberg decided to branch out. In 1998, they started Appraisal Specialists MidWest, the self-proclaimed "foremost personal property appraisers of the Twin Cities." After an appointment is scheduled, Kevin and Bonnie will go to their client's house and appraise the value of anything from artwork to stamps to furniture. Their "Treasures Uncovered" radio show, in the same vein as the "Antiques Roadshow" TV program, is featured regularly on Kare 11 and WCCO. Call them to see if that age-old, throwaway coffee table might actually be worth keeping around.
