Browning does not make firearms, FN does.
The value of ANY firearm is based on the exact make, model and condition. You have told us the make. Browning has been making firearms for about 138 years, and there are dozens of different models. I would suggest that you take your shotgun to a dealer or to a gun show for a hands-on assessment. Without you providing information to us, an answer is not possible.
