Take a look at the Blue Book of Gun Values at a nearby gun shop. Someone there will be able to help you. I can tell you they made a ton of these shotguns over the years, and it is not likely to hold any collector value. This is a good field gun for hunting.

The Blue Book of Gun Values tells all.

Yeah...what do you need to know? Not very specific.
