Simply means that whilst you might not value an item, somebody else will.

This is parallel to the saying "one person's meat is another person's poison." It means something that is good for someone is the opposite for others, reflecting circumstances, preferences, and other factors determine what one perceives as beneficial or detrimental.

It means that something one person considers useless can be valuable to someone else.

It means don't throw things that you don't want anymore away,as it may just be what someone else is looking for.
