In financial matters what best describes a silver standard?

A silver standard is a monetary system where the value of currency is directly linked to a specific amount of silver. In this system, coins or paper money can be exchanged for silver at a fixed rate, thereby establishing a stable value based on the precious metal. This standard contrasts with the gold standard, where currency is backed by gold. The silver standard was historically used by various countries but has largely been replaced by Fiat currency systems.
