Before anybody can give you anything like accurate information, you'll have to provide the board with more information. There are several different determining points with Winchester model 70's that can significantly affect the value.
1. Pre WWII?
2. Post WWII, to 1952.
3. Pre 1964
4. USRAC gun
5. FN New Haven gun
6. Current production gun
Anything pre-64 will have a Mauser type claw extractor, but will be right hand bolt only, blue steel and wood only. Many post 64 guns are push feed without the claw & bring less money. Is it a wood stock, or synthetic? Stainless steel, or blue?
As you can see, your original question is like asking: "Hey, I've got a Ford, what's it worth?"
