bimetallism

Bimetallism is an economic system that uses two metals, typically gold and silver, as the basis for a country's currency. Under this system, both metals are established by law to represent a fixed value in currency, allowing people to exchange money for either metal. This was historically used to stabilize the economy and ensure a stable money supply. Bimetallism aimed to prevent inflation and promote trust in currency by providing a tangible value behind money, distinguishing it from purely fiat currencies that are not backed by physical commodities.
