Requires professional appraisal
This should be a Browning Auto-5 Magnum. It was made in 1967 and should have Magnum engraved on the left side of the receiver.

Superposed shotguns are very collectable when in top condition. Values have a wide range due to so many variations and grades of the Superposed and other Browning Over/Unders. 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. Recommend taking it to a gun shop for appraisal.
The grade I Browning bl-22 is valued at between 150-295 dollars based on it having between 60%-90% of its original finish remaining,and a good bore.If you have the grade II(scroll engraved blue receiver,and deluxe high gloss wood) then the value would be 160-300 dollars.
Check the receiver and barrel
Depends on condition and whether it has the original box and papers.
