Silver – $884.95/Kg

Most of us think of silver as just a part of jewelry, but this versatile element has plenty of uses other than just looking fancy. If it wasn’t, this precious metal wouldn’t be worth nearly nine hundred dollars per kilogram.

Some of the purposes of silver are more traditional such as forming part of investments or currencies, and other uses are a bit more modern. Take, for example, the fact that this metal of antiquity is not only the most conductive one out there but is also used in appliances such as solar panels today.
