The Han records state that in 115 BC the mints in the capital were requested to cast Chi Ce coins, with one being worth five local coins. Only these were to circulate. Chi Ce means Red (or Shining) Edge, referring to the red copper showing when the edges were filed smooth. Some examples of this coin were found from the tomb of Liu Sheng, Prince of Zhongshan, who died in 113 BC.

The Han Dynasty (206 BC - 220 CE) was the second imperial dynasty of China, preceded by the Qin Dynasty (221-206 BCE) and succeeded by the Three Kingdoms (220-265 CE). It was founded by the peasant rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han. It was briefly interrupted by the Xin Dynasty (9-23 CE) of the former regent Wang Mang. This interregnum separates the Han into two periods: the Western Han (206 BCE9 CE) and Eastern Han (25-220 CE). Spanning over four centuries, the period of the Han Dynasty is considered a golden age in Chinese history.
