I have 4 of Winchesters Big 5 series safari rifles. The 338,416,458,and 470. They are obviously 100 percent. I have been thinking about selling them, as I would rather have something in my gunsafe I could use, not just look at. Thank you, Travis.

Look them up in the Blue Book of Gun Values.
This should be a starting point. I think they are a bit optimistic, but a start.
The actual value of a particular gun is set when a seller and a buyer agree upon a price. All else is conjecture.

cabelas shows a 5 gun set for $35k.... theres' another set on GA for $45k...

Wow, they must be matching serial numbers. Thanks jimatcat. So I guess close to 4k per rifle isn't out of line then. Travis.
