Local pricing as individual pieces, depending if at the "going rate", the "gouging rate", or the "it's your risk and we both know it" rate......
Anywhere from about $270 to possibly 3x that, if you could find folks who wanted each and every piece.
I ran thru the pics and mentally added up based on local pricing, kinda figuring the lowest and highest price I felt was reasonable, and tacking on for the folks who are convinced it is all "rare specialty stuff".
realistically, up to about $500, as individual pieces, if you didn't have to sell by a given time.
That depends on whether they are in good condition.... as junk, the mics are parts pieces, at a couple or 5 bucks a pop, for instance.
