I see them with price tags from about $1200 up to $2200 at the gun shows, Cabelas gun library, etc.
Personally, if you wanted to actually sell it within a reasonable period of time I am thinking you put the $1200 price on it and see what kind of offers you get. I'm guessing it would go for $800-1000. Condition is everything and, while that is a cool and iconic rifle, it is not in good condition.
I learned long ago you can't reason someone out of something they don't reason themselves into.
