Ban Liang: Qin Dynasty Coins

The “Qin Ban Liang” was a currency issued after the unification of the Qin Dynasty. Before the unification of the six states by the Qin Dynasty, various states had different shapes of coins, such as spade coins, knife coins, ring coins, etc. These coins could only circulate within their respective jurisdictions. After the unification of the six states by Qin Shihuang, he established unified laws, weights and measures, currency, and script. The old coins from the late Warring States period were abolished, and improvements were made to the Qin Ban Liang based on the coins used during the Warring States period. The round coins with square holes of Qin Ban Liang became the standard currency nationwide, putting an end to the chaotic state of diverse shapes and disparate weights of ancient Chinese currency. Qin Ban Liang was the first nationally unified currency in China, marking the initial maturity of ancient Chinese coins. Its emergence signified the standardization and regularization of currency casting and usage in ancient China, having a profound impact on the subsequent development of currency.

The symbolism of the Qin Ban Liang can be summarized in several aspects:

Unity and Standardization: The emergence of the Qin Ban Liang marked the initial maturity of ancient Chinese coins and served as a milestone in the development of Chinese currency. Its uniform format and weight symbolized national unity and standardized measures, facilitating commodity circulation and economic transactions.

Wealth and Auspiciousness: The round shape with a square hole of the Qin Ban Liang symbolized the concept of “heaven is round, earth is square,” signifying wealth and auspiciousness. Additionally, the alloy material of copper and tin, with copper considered an auspicious element in ancient times, further conveyed notions of prosperity and fortune.

Mystery and Power: The casting and usage of the Qin Ban Liang were associated with the religious beliefs and mythical legends of the Qin Dynasty, adding a certain mysterious aspect. Moreover, the inscriptions and patterns on the Qin Ban Liang reflected notions of strength and authority, symbolizing the power and dignity of the ruling authority.

Heritage and Commemoration: As an integral part of ancient Chinese currency, the Qin Ban Liang has a rich history and cultural background. Its collection and preservation not only show respect and commemoration for history but also contribute to the promotion and inheritance of Chinese culture.

In summary, the symbolism of the Qin Ban Liang encompasses unity, standardization, wealth, auspiciousness, mystery, power, heritage, and commemoration. These symbolic meanings are closely intertwined with the historical, cultural, and social context of the Qin Dynasty, providing an important window for understanding ancient Chinese culture and history.

The emergence of the Qin Ban Liang marked a significant milestone in the early maturity of ancient Chinese coins, representing a pivotal moment in the development of Chinese currency over more than two thousand years. This distinctive square-hole round coinage system influenced surrounding countries and persisted until the late Qing Dynasty and early Republic of China when it was replaced by machine-struck copper coins.

The bronze coin known as “Qin Ban Liang” features a “round with a square hole” design. The square hole represents the land, while the outer circle symbolizes the heavens. The combination of a round shape within a square hole signifies the ancient cosmological worldview of a round heaven and a square earth. This interpretation is widely accepted, although some argue that the circular shape within a square hole was a practical necessity for production, facilitating transportation, circulation, and storage – a standardized and practical form developed through continuous practice.

The inscription “Ban Liang” in seal script on the bronze coin was written by the famous Qin statesman Li Si. It signifies the weight of each coin, which was half a liang during that time, equivalent to twelve zhu, hence the name “Ban Liang Qian.”

According to historical records cited in “Shi Ji Ping Zhun Shu Suo Yin,” Qin coins were half a liang in weight, with a diameter of one inch and two fen, weighing twelve zhu. However, surviving Qin Ban Liang coins exhibit variations in size and weight, generally having a diameter of 3.2-3.4 centimeters and weighing around 8 grams. The coin’s inscription is raised, slender, and slightly arched, lacking inner and outer rims, with a plain back. Some examples weigh over 10 grams and even exceed 20 grams, possibly corresponding to the “hundred qian” coins mentioned in the historical records.

The Qin Ban Liang is crafted from an alloy of copper and tin, commonly referred to as “bronze.” During the Qin Dynasty, copper and tin were among the most crucial metallic materials, and bronze, known for its high hardness and resistance to wear and corrosion, was well-suited for producing items requiring prolonged use, such as currency.

In the production of Qin Ban Liang, the ratio of copper to tin was typically around four to one, ensuring the quality and hardness of the coin. The manufacturing process involved heating and melting the copper, then pouring the tin alloy into the molten copper, stirring the mixture before pouring it into molds to create circular thin pieces. The final coins underwent processes like grinding and polishing before being ready for use.

In addition to copper and tin, Qin Ban Liang may also contain small amounts of elements like lead and iron. These elements could undergo reactions with copper and tin during the casting process, resulting in slight variations in the composition and color of the Qin Ban Liang. Furthermore, the manufacturing process required careful control of parameters such as temperature, time, and alloy ratios to ensure the quality and stability of the currency.

In summary, the Qin Ban Liang is made from an alloy of copper and tin, chosen for its properties, and the manufacturing process is designed to guarantee the coin’s quality and durability. The production techniques and casting technology of Qin Ban Liang have also influenced the minting of currency in subsequent periods.

During the Warring States period of the Qin Dynasty, coins were predominantly circulated with military expeditions and had minimal circulation in commercial activities with the six states. They were often discovered along the routes of Qin’s military campaigns, such as the “Golden Ox Road” to Shu, the “Commerce Road” to Chu, and the “Yiyang Road” to Han and Wei. As a result, the coins were heavy, and their circulation range was limited. The coin types were mostly large (with a diameter of over 3 centimeters).

Upon inheriting the practices of previous rulers, Qin Shi Huang continued to use Ban Liang coins. When Qin standardized currency, the central authority also minted “heavy as its inscription” Ban Liang coins. These coins were characterized by a slightly larger diameter (above 3.3 centimeters) and a slightly thinner profile compared to earlier versions, weighing around 8 grams.

As the state’s fortunes declined and the need for market commodity circulation arose, coins were subsequently reduced in size and weight. By the late Qin period, coin types became smaller, with diameters mostly below 3 centimeters and weights around 3-4 grams.

After Gaozu of Han unified the country in 206 BCE, in the early post-war stabilization period, the economy urgently needed recovery. Although the Ban Liang coins inherited from the Qin Dynasty were still used, their weight posed difficulties. This led to private casting of “Jia Qian” coins, contributing to rampant inflation and the malicious devaluation of currency. By the second year of Empress Lü’s reign (186 BCE), the Ban Liang was reintroduced, but subsequent changes were frequent, with varying sizes and weights despite the inscriptions indicating “Ban Liang.”

The Ban Liang of the Qin Dynasty retained the same inscriptions as those from the Warring States period, with minimal changes in coin types but improvements in minting technology. Private cast coins often contained impurities, making them difficult to distinguish. Official coins were typically processed, with seal script inscriptions having square turns, presenting neat and evenly sized characters. Ban Liang coins unearthed from Qin Dynasty tombs and hoards in Shaanxi, Inner Mongolia, Hubei, and other regions can be roughly categorized into three types based on their size and weight: the first type has a diameter above 3 centimeters, similar in size to ordinary Warring States Ban Liang coins, minted in the early Qin Dynasty; the second type is smaller, with a diameter below 3 centimeters, mostly around 2.7–2.8 centimeters, minted in the late Qin Dynasty; the third type is inferior small coins, known as “Jia Qian,” referring to Yujia-shaped small coins from the early Han Dynasty, with specific time and meaning, weighing below 3 grams, and even as low as 1 gram.
