In 1071 the government issued large 10-cash coins to meet military expenses. Later, illicit coining forced the government to devalue these coins to 3 cash and than (in 1073) to 2 cash. The 2-cash coins were cast until 1077.

The Song dynasty was a Chinese dynasty that ruled from 960 to 1279 and is renowned for its economic prosperity, technological innovation, and cultural achievements. Divided into the Northern Song (960–1127) and Southern Song (1127–1279) periods, it oversaw major advances in printing, gunpowder, navigation, and commerce. The Song economy was among the most developed in the medieval world, with thriving cities and extensive domestic and international trade. Despite its cultural and economic strength, the dynasty ultimately fell to the Mongols under Kublai Khan in 1279.
