How can i find out the value of a "used" gun for free, is there a book/list like used for cars?

yes.

Thanks Tony, is there one that's free?

They sell gun value books in Barnes and Noble for a couple bucks. I know it's a bit shady, but you could go and "look up" the price. I only did it once for my fathers' Winchester Bi-Centennial because it's a hard gun to price.

 

I'm not sure if the library would have this same book. Possibly one of the "super libraries" in the larger towns.

 

Other than that.. I look on Gunbroker, or GunsAmerica to see what they are going for.

I use gunbroker. It is most up to date as to PRESENT needs. Prices changes everyday.

you can go to another gun site, look up the model & check prices:
