Value of a gun is based on 3 items. Those are make, model and condition. We need all 3, You gave us none. Good questions equal good answers. Yours is not a good question.
Depends on which gun and condition, condition, and condition...
date a gun
What model is it. How old is it, what condition is it in, is it still working?

dude not trying to be mean, but what gun are you talking about dude! if i had a gun i could tell u how much its worth, and also you could do it yourself!
It could be anywhere from 30-100 years old and worth 50-300 USD
No gun killed Lincoln.
Not old enough to be worth much at the gun show but definitely old enough to hang on to. Just my thoughts.
