Very difficult to predict auction outcomes but in general aftermarket auctions return much lower values than expired domain auctions. I think the domain is nice but if I were to guess, I'd guess around $1,000. You can try and get a sense for the value at auction by using a reserve on a site that supports it, e.g: Atom allows auctions with a reserve. Put the domain for auction at Atom with a very high reserve and see what happens.
