Well you can (as other have suggested):
1) Hold on to them. if they are weapons you may use, you can use some to upgrade down different paths.
2) Hold to feed to frampt when you get him, not sure how many souls you get, though it wouldn't hurt. http://darksoulswiki.wikispaces.com/Kingseeker+Frampt *May have some spoilers, use the link only if you are comfortable with that.
3) Drop them in the hopes of making vagrants, wandering hostile items that invade other peoples worlds. If those players beat them, they get rewards, usually in the form of humanity. http://darksoulswiki.wikispaces.com/Vagrants
4) Drop in an invaders world or in your world when you meet an invader, people like getting presents
.
5) Give them to Mildred so that she can give them to others via her store of the damned
