Serial number 3Z4489 was made in 1963, not in 1954. 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 recoil pads (other than Mag 12's) poly-chokes and compensators will reduce value. This gun has an aftermarket choking devise which hurts the value. A potential buyer may consider it as a shooter, but it is no longer collectable, no matter the condition. Recommend taking it to a gun shop for appraisal.
Go to Browning.com and select customer service. Then select date your firearm. What it's worth depends on condition, gauge, accessories, barrel length and what it is choked. You don't address any of these. Broad range from 200-400 USD.
