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. Recommend taking it to a gun shop for appraisal.

A Browning over and under is worth about $1,000-1,500 on it own and the fact that it's a Belgium made Browing increases the price significanly. I would say somewhere in the range of $500 to $750 more. The belgium made Browning is the most collectible and popular.
If you have a Browning auto-5 shotgun in 16 gauge(you do not state)then it was made in the year 1928.
If it was made in Belgium, it was a custom order. No way to estimate value. You will need the services of a professional firearms appraiser.
