This is a monetary weight from the Western Han dynasty, used to weigh the circulating “four-zhu banliang” coins of the time.
The weight takes the form of a horizontal rectangular plaque, with a protruding section at the top bearing a perforation, enabling it to be suspended from a balance beam. The obverse is inscribed with the characters “Xi □”, which, when compared with inscriptions found on coins, are likely to be read from left to right in reverse. The second character is severely eroded and illegible; characters with vaguely similar structures include “Bi” (畢), “Zhou” (周), or “Gu” (固), though these are offered only for reference. According to similar unearthed coin weights, this inscription may refer either to a place name or to the name of an official.
The reverse is engraved with the characters “Si zhu” (四朱), a variant form of “Si zhu” (四銖, meaning “four zhu”), also to be read from left to right in reverse. In practical use, the coin and its corresponding weight would be threaded together with a string, which would be placed at a designated mark on the beam of the balance to determine the correct weight. This coin-weighing method formed a crucial part of the laissez-faire minting policy implemented during the reign of Emperor Wen of Han. Archaeological analysis indicates that the average quality of coins minted during the reigns of Emperors Wen and Jing was significantly higher than that of the early Han period and even superior to coins produced under Emperor Wu and his successors.
The reason the monetary system did not suffer a collapse in overall credibility—unlike many other dynasties plagued by rampant private minting—may lie precisely in the strict enforcement of this coin-weighing system. It prevented inferior coins from mingling undetected among superior ones, as their discrepancies would be revealed in the course of weighing, effectively resulting in a phenomenon opposite to Gresham’s Law, wherein good money drove out bad.
Emperor Wen of Han, named Liu Heng, was the fifth emperor of the Western Han dynasty and the fourth son of Emperor Gaozu (Liu Bang). He reigned from 179 BC to 157 BC. Upon ascending the throne, he continued the policies of his father, as well as those of Emperor Hui and Empress Dowager Lü, adopting a governance style marked by minimal taxation and lenient labour obligations, with the aim of allowing the people to recuperate from the ravages of war. He is regarded as one of the principal architects of the “Rule of Wen and Jing”.
Emperor Wen’s reign was characterised by political clarity, personal frugality, and a concerted effort to restrain the power of local magnates and reform bureaucratic administration. He placed strong emphasis on the rationality and enforcement of law, even personally revising statutes to reduce the severity of punishments. Following the Daoist philosophy of Huang-Lao, he governed by non-intervention, which led to a prosperous treasury, social stability, and improved living conditions for the populace. His economic policies included monetary reform, notably the minting of the “four-zhu banliang” coin to stabilise the currency system.
Throughout his reign, he refrained from launching large-scale military campaigns, allowing the national economy and strength to recover steadily, thereby laying a solid foundation for the expansionist policies pursued by Emperor Wu. After his death, he was given the temple name “Wen” and, together with his son Emperor Jing, is remembered as part of one of the most renowned periods of good governance in the early imperial history of China.
