Religious people- question for you?

We moved into a new house and there was a large crucifix left on the top shelf of the bedroom closet. We want to get rid of it so we can use the shelf, but I'm not sure the proper thing to do with it. We are not religious, but want to be respectful in the way that we get rid of it. Is it ok to donate it to goodwill or some place like that? Like I said, just want to make sure it's done respectfully.
