[QUOTE="satootoko, post: 170780, member: 669"]Clad coins consist of bonded measureable layers of metal which are mechanically squeezed together under such force that they stick to each other. The actual weight of each component metal is known, and is a significant percentage of the total weight. Plated coins have a solid core and a coating deposited molecule by molecule, which is too thin to measure without extremely sensitive instruments. The weight of the plating is an insignificant percentage of the total weight. If the core metal has a higher melting point than the outer metal, the core can also be quickly dipped in molten outer metal, resulting in a much weaker bond between the core and the covering, allowing the core to be seen through a slight scratch on the object's surface. Hardly "all the same" IMHO.[/QUOTE]
