On ladder, my guess is that it's best sell the Gris corona and the BK sword right now, as long as there are more people who try to complete these sets than there are items offered.
Regarding the BA, I guess you mean an unid DC, right ? That one is worth far more than Um IMO. People are starting to equip zealots and smiters to fight the Übers, and that's a great weapon for that job. I suggest to ID it and consider to keep it for yourself.
