I have only one quilt made by my gr-grandmother, and although it is in bad shape, I cherish it and wouldn't get rid of it for any money. But if you have a lot, as you said, it wouldn't matter. If they are at all intact, you could cut some good spots out and make a couch/throw pillow. You could cut a piece from each one and make a commemorative display in a frame or shadow box. You could give them to an animal shelter to use for bedding, or toucan just throw them away too.
