Impossible to answer.
Could be anywhere from 50-50000 USD depending on EXACTLY what it is and the condition.
No such shotgun model number/
Value of gun= make+ model+ condition. You gave us none of the 3. The serial number conveys no information.
What Make? What Model? what condition?
No way to tell. The serial number does not tell make, model, and condition.
Depends upon the condition of the gun and the area of the country you are trying to sell it. FYI, it is a 2005 model.
Which model are you referring to? State the model number and the condition of the gun, so and estimate can be given. Falke made 10 different air guns and rifles.
you need to state the model number not the serial number to get and estimate of value.
I believe this is a rifle not a gun. Go back and look again for the model number. I think you are giving the serial number and that doesn't help.
Both Daisy and Crosman air guns made BB guns for Sears. you will have to state the model to get an estimate of the value. Check the model number on the gun, any model that begins with 126 was made by Crosman air gun and any model that begins with 799 was made by Daisy air gun.
the trapdoor model...................
It would be worth around $105
