This refers to the “Yongzheng Tongbao,” a square-holed coin issued by the “Bao Yuan Bureau,” an institution established by the Ministry of Works during the reign of Emperor Yongzheng, the fifth emperor of the Qing Dynasty, who ruled from AD 1722 to AD 1735.
The coin’s outer and inner borders, as well as the central square hole, are well-defined. The obverse side features the four Chinese characters “Yongzheng Tongbao” inscribed in regular script within the inner border. On the reverse side, the inner border contains the Manchu script “ᠪᠣᡠ ᠶᡠᠸᠠᠨ”(Boo Yuan), indicating the Bao Quan Bureau. The edge of this copper coin is wider compared to another coin also from the “Bao Yuan Bureau.”
The Bao Quan Bureau and the Bao Yuan Bureau were the primary institutions responsible for minting coins during the Ming and Qing Dynasties. The establishment of the Qing Dynasty’s Bao Yuan Bureau can be traced back to the first year of the Shunzhi reign (AD 1644), when it was created to mint the “Shunzhi Tongbao” coins. At that time, the Ministry of Revenue set up the Bao Quan Bureau, primarily to produce coins for military expenses, while the Ministry of Works established the Bao Yuan Bureau to mint coins for use in construction projects.
In the early Qing Dynasty, the minting policies were not yet standardised, resulting in frequent changes despite the existence of basic guidelines. The Qing Dynasty primarily used silver as the standard currency, with the official rate set at “one tael of silver for every 1,000 copper coins.” However, due to fluctuations in the composition and weight of the copper coins, the exchange rate between silver and copper was unstable, severely impacting commerce and the livelihoods of the people. Consequently, during the reign of Emperor Yongzheng, reforms were undertaken in the monetary system to strengthen the nation’s fiscal stability.
After the minting system was standardised, addressing the frequent adjustments in the size of copper coins that had occurred during the Kangxi period. Clear regulations were established regarding the weight of copper coins, the ratio of copper to lead in the alloy, the pricing of copper and lead used in minting, the quotas for coin production at various mints, the materials used, and the wages paid to furnace workers. Notably, the weight of copper coins was standardised at 1.2 qian, which was considered moderate and became the official standard. This reform ended the coexistence of copper coins with varying weights in the market, which had complicated exchanges, and thus facilitated the circulation of currency, promoting the development of the commodity economy.
To reduce the cost of minting coins, Emperor Yongzheng ordered the exploitation of copper from Yunnan and lead from Guizhou during his reign. The Qing government tightly monopolised the entire process of copper and lead production, procurement, and sales. As a result, domestic copper from Yunnan and lead from Guizhou were exclusively used for coinage, replacing previously imported foreign copper and Japanese lead as the primary materials for minting coins.
As a result of the currency reforms during the Yongzheng period, the cost of minting coins was significantly reduced in the subsequent Qianlong era. This allowed for an improvement in the exchange rate of one tael of silver to copper coins, increasing from the Yongzheng ratio of 1:700-800 to 1:900. The rise in the market value of copper coins and the corresponding increase in purchasing power had a positive impact on various social classes, including soldiers, officials, and craftsmen.
