This coin is identified as the “Si Zhu Ban Liang,” which was likely first cast in the fifth year of the reign of Emperor Wen of the Western Han dynasty (175 BC) and remained in circulation until the first year of the reign of Emperor Wu (140 BC).
The outer rim and inner border of the obverse appear intermittently, while the horizontal lines at the top and bottom of the square hole are relatively distinct. In the upper right portion, an area lacking patina may indicate damage. The obverse bears the inscription “Ban Liang” in seal script, to be read from right to left. Both characters are connected to the rim and the edges of the square hole. The strokes exhibit angular turns, with uneven thickness, and the composition is sparse at the top and dense at the bottom. The height of the characters is nearly confined within the vertical span of the square hole. The character “Ban” is positioned slightly lower than “Liang”, a feature referred to as “Lowered Ban”. The first stroke of the character “Liang” aligns with the width of the left-side component “Jiong”. The two “Ren” components in the middle of “Liang” are placed closer to the base of the character and arranged in a tri-radial pattern. These components are connected to the strokes of the “Bi” radical, a configuration sometimes referred to as “Double Ren Liang”. The reverse is plain and uninscribed, and also exhibits signs of damage. The edge of the coin appears to have been lightly filed or polished, contributing to its refined appearance. Coins exhibiting these characteristics have been unearthed in various locations, including Yongcheng, Yichuan, Xinzheng, Zhengzhou, and Mengjin in Henan Province; Fenghuangshan in Jiangling, Hubei; and Linxia in Gansu.
The term “ban liang” originated during the Warring States period, when such coins originally weighed half a liang (approximately 7.81 grams today). By the late Qin dynasty, their weight had been reduced to eight zhu (approximately 5.21 grams). However, by then, the term “ban liang” no longer referred to either the denomination or actual weight, but instead to the standard form of the coin—round with a square hole in the centre. According to the “Treatise on Food and Money II” in the Book of Han, “In the fifth year of Emperor Xiaowen’s reign, as coins became increasingly numerous and lightweight, the government began recasting four-zhu coins, inscribed with ‘ban liang.’ The ban on private minting was lifted, and the people were permitted to cast coins.” The phrase “coins became increasingly numerous and lightweight” refers to the “elm-seed ban liang” coins of the early Han dynasty, also known as “seed coins,” which were light, thin, and featured large central holes. Although these coins bore the same “ban liang” inscription, their official weight was only three zhu, prompting public dissatisfaction with their lightness. Subsequently, Emperor Wen lifted the ban on coinage, allowing the people to cast “ban liang” coins modelled to weigh four zhu. Consequently, there exists a wide variety of stylistic versions of the Si Zhu Ban Liang, too numerous to enumerate. Nonetheless, due to effective regulation and oversight, the phenomenon of inferior coins driving out superior ones did not materialise. Coins attributed to Emperor Wen’s Si Zhu Ban Liang unearthed in archaeological contexts consistently weigh slightly more than the official standard of four zhu (approximately 2.6 grams). In 140 BC, the first year of the reign of Emperor Wu, the government introduced a new three-zhu coin. That same year, the coinage ban was reinstated, with the edict: “Those who illegally mint any type of metal coin shall be sentenced to death; violations by officials and civilians were too numerous to record.” After several policy reversals, the currency system was eventually unified under the five-zhu coin standard.
Emperor Wen of Han, personal name 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 Liu Bang, as well as those of his predecessors Emperor Hui and Empress Dowager Lü, adopting a governance style characterised by reduced taxes and corvée obligations, and a philosophy of “reposing the people through rest.” He is regarded as a key figure in the establishment of the “Rule of Wen and Jing.” During his reign, governance was marked by integrity and frugality. He took measures to curtail the power of aristocratic families, reformed the bureaucracy, and placed great emphasis on the fairness and application of law, even personally amending statutes to reduce the severity of punishments. Influenced by the Daoist Huang-Lao school of thought, he advocated for a policy of non-intervention, resulting in a well-stocked treasury, social stability, and improved livelihoods for the populace. He also implemented monetary reforms, such as issuing the “Si Zhu Ban Liang” coin to stabilise the currency system. Emperor Wen’s reign saw no large-scale military campaigns, allowing the state’s overall strength to gradually recover and laying a solid foundation for the subsequent territorial expansion under Emperor Wu. After his death, he was posthumously honoured with the temple name “Wen,” and together with his son Emperor Jing, is remembered as one of the most exemplary rulers of the early Chinese imperial era.
