Wow. I don't even remember that story - guess the site bombed in the worst possible way if no one remembers it.
I'd hold onto it awhile for unique bragging rights and a story of your own. And who knows? The original registrant might want it back or someone else might want to build a business around it. I'd get a page up with a for sale link ASAP.
But if no one comes to you to buy it, I'm not sure it has a lot of $ value on its own right now.
