S&W Chief's Special 9mm Double-Action only

What would be a reasonable price range for selling a S&W Chief's Special, 9mm, stainless steel, double-action only, model CS9 pistol, bought new in 2004, and is now currently in what would be described as excellent condition? Also, original paperwork, case and three 7-round capacity magazines also included. Thanks for your advice and input! -JAK
