You would have to be more specific with details as to date of manufacture, overall condition, etc. The pre-1964 Winchester Model 70 are generally more desirable than the post-64 rifles, and that can drive the value up.
depending on condition, anywhere from $100 to $1000. These ARE collectable firearms, but value is based on condition and originality.
