As currency
Silver has currency function, and like gold, it was used as currency for a long period of time in human history. Gold standard was once adopted in the history of world currencies, but silver standard was never adopted. Silver faded out of circulation due to reforms in the monetary systems and the emergence of currencies backed by credit. Nowadays, minted silver coins are mainly used for investment or commemorative purposes. In addition, investment in other silver objects such as silver bullion has been continuously increasing.

Industry and high-tech industries
Silver has the best electric and thermal conductivity, good flexibility, ductibility and reflectivity, and it’s playing an increasing role in industrial sectors and for decoration. Silver is mainly used in industries including electrical and electronics, photography, solar energy and medicine, and is also used in the production of jewelry, silverware and silver coins.

Silver's versatility makes it irreplaceable in most industries, especially in high-tech sectors that require high reliability, accuracy and safety.

Silver can be used in thick film pastes, while mesh-like and crystalline silver can be used as a catalyst for chemical reactions. Silver nitrate used for silver plating can apply to glasses-making. Silver iodide can be used to produce artificial rain.

Silver ions and silver compounds can kill or inhibit bacteria, viruses, algae and fungi, with effect similar to that of mercury and lead. Because silver has such toxic effect on bacteria and virus, it is also known as biophile metal.
