Smith & Wesson has produced many models of the .357 magnum revolver. So I would need much more information. The model number can be found on the frame under the yoke or in layman terms, under the thing that holds the six revolving chambers. Of course the finish on the revolver (very dark blue, nickle or silvery stainless steel) is a factor as well as the condition of the gun (rusty, lots of dings and the like). Ball parking the whole Smith and Wesson revolver market from older average condition gun at about $200 to the stainless J, K and N frames at about $600.
