Is it wrong or improper to give away wedding presents that are not being used?

My husband and I have many wedding presents that we have not opened and do not see ourselves opening until many years from now. We got married in July 2007. Would it be wrong or disrespectful to drop these things off at a Goodwill or Salvation Army or seek out a friend who could use some of these things? We don't have the space to store these things long term. Please...no mean answers. Thanks.
