You should be content if you get mid $XXXs, like they said even ones with no sub-premium letters sometimes sell for $350 or so (like the Y in yours, interesting case, because despite being a non-premium letter it's the only consonant that can act as a vowel as well, and that actually makes your acronym pronounceable, so make sure you stress the pronounceability of it when you list it) I'd say if you're lucky you might get the right buyer paying like $750 .....but that's a bit optimistic - the novelty of the 2-char .biz domains kind of wore off already ...
Not long after the two-char .biz domains (previously not available) were introduced to the masses the NN.biz and LL.biz types were selling (or at least the sellers were asking) $10K+ easily, if the letters are superb or it's a great pronounceable short acronym you still find those quoted well into the $X,XXX. The ext is not a great one, don't forget that, but .info, .us and most of the newer exts do not allow two-char domains in those exts, they all start at three char's. That's why to this day I still get good offers for our CC.cc's and I still want to get my hands on a LL.cc or NN.cc if I can pay that.....
Don't sell VY.biz to quick if you don't get a decent offer, I'd sit on it til a good one comes along (it also depends on what you paid for the thing....)
