It will depend when/where you sell. Sell soon, since high-end toons haven't made it to market for the most part. Prices may rise just a tick before House of Thule comes out, but they'll drop dramatically after that unless they have all the relevant flagging and access.
If you sell here, prices tend to be lower but there are no fees and buyers are generally trustworthy. PlayerAuctions allows you to have a higher list price, but you pay on the order of 15% in fees, and the site sucks in major ways.
Anyway, my rough estimate would be about $1000. I haven't seen anything sell for more than this recently. It's possible you could find a very motivated buyer since warriors are in high demand.
Good luck.
