It's not possible to answer the question as asked. There are too many types, models and variations of these guns to consider. These guns can sell for as little as a few hundred dollars up to thousands, depending on what it is, when it was made and condition. Condition is everything when appraising a gun. As always, it's recommended that you have it appraised at a Gun Shop or qualified professional.

If your over under shotgun was made prior to 1964,then the model of your Browning shotgun should be named the superposed.
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.
Yes, Browning has made the Superposed Lightning in Belgium.
