Would need a model name to answer.
value depends on overall condition, however, the rosco has little value...........
Assuming it is .38 caliber and therefore a J-frame, and without knowing condition, $150-$300
Need a better description. Is it a pistol or revolver? What are the markings on the barrel or slide? is it a single action(cowboy gun)? is a double action(police gun)?
