This question needs to be narrowed down to Model, make, guage or caliber and also condition. There are dozens of Belgian made models and values ranging from $200 to over $30,000.
Value of any gun is based on exact make, model and condition. Without that information, we cannot even make a good guess. Sorry-
$150 to several thousand dollars, depending on condition,markings, and history of the gun.
Impossible to value with just a serial number.
100-2000 usd
Please state the model.
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.

50-500 USD or so
$450-$750
500 USD
