The "Silver Standard" is a monetary system where the value of a country's currency is directly linked to a specific amount of silver. In this system, silver coins or bullion are used as legal tender, and the government guarantees that it will exchange currency for silver at a fixed rate. This standard was used by various countries in the past, particularly during the 19th century. Countries that adopted the Silver Standard aimed to stabilize their economies and facilitate trade. However, it faced challenges, such as fluctuations in silver prices and competition with the Gold Standard. Eventually, most nations moved away from the Silver Standard in favor of fiat currency systems.
