That depends on condition. Can you post some pictures? That will help me determine a more accurate value range. Without seeing it I can say most fall in the $200-450 range (the pistol alone) magazines are in the $75-125 range and the holster could be $25-250 or more depending on condition and makers markings. As you can see there is a wide range or what it could be wourth and without seeing what you have it is hard to narrow it down. Also the retail value is not necessarly what you could get for it if you were trying to sell it.
