It's in good condition. Check reverb.com for pricing on similar ones. I buy/sell/trade old guitars.
Things to take into consideration: This is a Strat, so it has a lot of people that like it. As a vintage guitar, it's a post-CBS Fender, meaning, it is a model made after 1968 - CBS bought Fender and did a lot of cost-cutting. (Same thing happened to Gibson with a company called Norlin around the same time).
So, point being, a CBS Fender is going to be less valuable than a pre-CBS. It's also a 3-bolt neck. I personally prefer that, but many people have a strange prejudice against the microtilt necks.
I'd say between $2500-$4500, but leaning toward the lower end.
The other person saying $4000-8000 is on crack.
