How much is an Ithaca 12 gauge shotgun worth that has never been fired and was bought in 1975?

Answer 1

Let's start at the top. What is the action: double barrel, single barrel breech loading, self-loading (semi-auto), or pump action? What markings are on the gun (i.e., model name/number, serial number). Does it have a vent rib? What choke? What is its condition ("unfired" means very little, since all guns are proof fired at the factory). Do you have the box and papers? All of this info is necessary to even make a guess over the Internet.
