Regarding backlinks, I have powerful backlinks from many sites because I am actually a web developer / designer that give free themes, so lot of EDU or GOV sites linked to me because they use my works.
That's the mostly likely reason, right there.
As for its worth, it will allow your site to rank well for almost anything you put on it. Ok, that's a stretch, but not too far off. It will also allow you to pass along some of that power to other sites you own. Starting a new site? Link to it from this one to give it a great big ol' push right out of the gate.
And finally, while selling links is "bad", that PR8 will allow you to get a higher price for advertising 9 times out of 10. Regardless of whether or not PR should be used in ad pricing, the fact is that buyers look at it. Until Google stops showing it, buyers will pay more for an ad on a PR8 site than they will on a PR2 site.
