Any ideas about what I should do with these swords?

During my martial arts practice I acquired a straight sword and a set of double swords. I don’t practice any more, these really have no sentimental value to me and I am not all that enthusiastic about having them hanging around the house, so it is time to get rid of them. I don’t want to pawn them or sell them on ebay and I am pretty sure the Goodwill won’t accept them as a donation. I’m also not liking the idea of throwing them in the trash or putting them on Craig’s List. Does anyone have any great ideas about what to do with these swords?
