Value is too difficult to be accurate without seeing the gun. Condition which includes the amount of original finish and original configuration will determine value. Auto 5's with poly-chokes, compensators and recoil pads (other than Mag 12's) will reduce value. Personalized initial such as "PV" will also decrease the value, more importantly, if the gund is in great condition the PV will decrease desireability. Recommend taking it to a gun shop for appraisal.
