If I were to ask you to name the most valuable thing in the world, ounce for ounce, you would probably say that it was gold, or platinum or perhaps diamonds or emeralds. In fact the most valuable thing in the world measured by its weight is a piece of paper. It's not just any piece of paper, it's a stamp printed in Sweden in 1855. Known as the Treskilling Yellow, it is thought to be the only postage stamp of its kind in existence and it recently sold for 1.2 million dollars. When one thinks of what 1.2 million dollars could do devoted to good causes, it seems an awful waste of money. Perhaps people put too much value on objects, and too little value on human lives and human souls.
