The world's most expensive object by weight
The British Guiana one-cent magenta stamp is considered the most expensive object in the world by weight, costing 8.3 million for about 40 milligrams. It is unique because it's a regular postage stamp, not an error, and it's the only one of its kind that has survived. This stamp was made locally for temporary use and was likely used to send newspapers. It's more valuable than things like antimatter because it's a single, unique object with a rich history, unlike substances that can be replaced. First found in 1873 by a 12-year-old, it is now owned by Stanley Gibbons and is displayed in an oxygen-free case, its value increasing with its fame.
