Actually, if you can not sell them because they are set or unique armour, then you must have found them in the current act. If you bring them into the next act, then you can sell them. I'd suggest leaving them in the BF; if you have room you can grab them at the end of the act to sell later, and if not, you're not loosing out on a great deal of gold by leaving them behind.
if only i'd known that at the start! <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" /> i just ditched them.
