The value of ANY gun is based on exact MAKE, MODEL and CONDITION. You have shared with us the make. Dan Wessons have a great variety of barrels, can be blued or stainless, and come in at least 4 variants and several different models.
For the basic blued heavy vented rib barreled gun made in Monson MA, about $500. FWIW, these are very under appreciated guns. Strong as a tank and extremely accurate- and overlooked by a lot of people.
