CBD/world is the type of new gtld that has the potential for 4 figs and above. I don't think there is much liquidation in it as ngtlds are still highly speculative for the most part, but in saying that I would probably offer you $100-200 for it.
I think considering what you paid for it you may as well keep it and see what happens. Wait for that offer. Up to you though.
Good luck.
