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. A rough ball park figure would be $350-$800 range for this gun. Near mint guns and original box will command an extra premium. Recommend taking it to a gun shop for appraisal.
