I see. Sadly in this case I would think that if it did have long missiles, it would make it more valuable, since it would help authenticate the release and make the toy unique. In terms of uniqueness, I've only found one other of these on the internet: http://www.flickr.com/photos/paulfri...7594327955633/. I would say that now is probably not the best time to sell it, with rereleased Sunstorms so readily available. And since it's not a recognised release it's really only as valuable as anyone is willing to pay for it, which is unfortunately hard to gauge. How much were you willing to pay for it in the first place? I would think it would still be about the same.
Why not send it to AFA? If they box it, it becomes legit to collectors and since it's so rare it could command a very high end price. It might be a bit of a gamble but it could pay off big time.
Definitely worth the effort to AFA grade that one. With the greatest respect, you'd be a fool to open him before grading.
