How Do I Dispose of Christian Religious Items After I Convert?

I grew up in a very religious Catholic family and attended Catholic schools through college. Through my upbringing, I accumulated a number of rosaries, bibles, and other accoutrements. When I started converting, I took all these things and put them in a box. My family is no longer religious whatsoever and also has no use for them. I didn't want to throw all these things away because this felt disrespectful, but I I feel uncomfortable still owning all of them. Is there a proper way to dispose of the items?
