I too was going to suggest giving what you don't want to a local guild who does charity work. I also love the idea of you choosing the ones you really like and making two sided quilts out of them. That way you get to enjoy some of them and honor the makers. Look for batting on sale and you won't have to put out too much money. It is so sad to see this happen but I think it happens a lot anymore. Good luck with whatever you decide. It is just so wonderful that they were offered to you and you were able to say "Yes, please!!!"
My favorites: #4 the pinwheel and #7 (don't know what to call that). Oh just happen to think, is there a museum near you that might be interested in them especially if they were made in your state/area? That would be a great way to preserve the tops for the future.
