What is a Coin?

A coin is a small, flat, round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. Coins are most often issued by a government and intended for circulation. Commemorative coins may be issued to celebrate an event or honor an individual.

Mineral is the naturally occurring solid material that makes up rocks and other geological features on Earth. It can also refer to any substance composed of atoms arranged in an orderly structure. Minerals form when molten rock cools and crystallizes, either at the surface or deep within the Earth’s crust. The study of minerals is known as mineralogy.

Minerals come in many shapes, sizes, colors, and chemical compositions. Some common minerals include quartz (SiO2), feldspar (KAlSi3O8), mica (KAl3Si3O10(OH)2), olivine ((MgFe)2SiO4), calcite (CaCO3), gypsum (CaSO4·2H20). Each type of mineral has unique physical properties such as hardness, luster, cleavage direction, color streak.

Mineral resources are essential for modern society – they provide raw materials for construction and manufacturing industries; they are used in agriculture and energy production; they are also important components of our everyday lives such as jewelry and cosmetics.
