Basically, they are free money. Though you can't use it for yourself, you can donate them to elementary schools where the future of America is getting educated.
Though I obviously do not have any children going to elementary school, or any children at all, I have started collecting them. Most of them expire in 2014. Hopefully by then, I'll have some sort of significant contribution to give to either a school in my area, or maybe my dear Shorewood Hills Elementary School in Madison, WI. Why throw away ten cent? I guess people do it a lot with real money, but it seems pretty silly to me.
This is my official challenge to all you readers to collect Box Tops for Education--mostly because, why not?
