Value is too difficult to be accurate without seeing the gun and dating it as well as which model of the A5's that it is. Condition which includes the amount of original finish and original configuration will determine value. Auto 5's with recoil pads (other than Mag 12's) poly-chokes and compensators will reduce value. Recommend taking it to a gun shop for appraisal.
