i would use them- if you really have no interest using wool batts- maybe stop by a lqs and talk to them there- maybe they have a bulletin board or newsletter and would let you (advertise) them-
i would not think anyone would pay alot for them- maybe 1/2 or what a new wool batt would run....
i love working with wool batts-they are my favorite- i pick up old wool blankets at yardsales-thrift stores just to recycle wool fibers..wool is so very nice to work with.
