This is like asking, "What's my car worth?" It cannot be answered without more information. Ask your question again with more detail. The prices of Browning shotguns vary greatly depending on the year it was manufactured, the condition it is in, the model, the gauge, and the type of action. over &under are the most pricey then auto loaders then pumps are the low end
100-10000 USD or more depending on specifics.
Your 1963 made Browning light weight 12 gauge shotgun cannot be given a value,without you providing a more detailed description of the shotguns overall condition;to include the metal finish,wood condition and the condition of the shotguns bore.Please include whether you have a plain barrel,solid matte rib,or vent rib barrel.
Browning did not make a gun as you described
This cannot be answered without a detailed description of the shotguns condition.
That is a broad question, as there are some dbl barrel 12 gauge shotguns worth $50.00-$75.00, and then there are bennelli and similar types worth $500.00 or more. Custom shotguns from Italy and Germany may cost as much as $20,000 to $50,000.
There were dozens of different shotguns made for Sears under the JC Higgins name. Your question is the equal of "what is a Ford car worth?"
It is worth as much as you can get. Most BB shotguns "wallhangers"and such are $100.00 and up.
Depending on condition, gauge, barrel length, choke; a few hundred to maybe a thousand
If the barrel is really 11 inches and you do not have a federal tax stamp to show for this gun it is worth about 10 years in prison, a $250,000 fine, or both. Shotguns with barrel length under 18 inches (measured from the breech face) fall under the NFA and must be registered with the ATF as short barrel shotguns and a $200 tax must be paid. The paperwork must be done before acquiring or making the gun.
That cannot be answered without you providing a detailed description of your shotguns overall condition including the amount of original finish remaining on the wood and metal.Also include the type of barrel with your shotgun,and bore condition.I can say that your Browning auto-5 20ga.shotgun is a magnum 20 gauge which was made in Belgium for Browning in the year 1967.
