This is a Chongzhen Tongbao coin cast in the name of Emperor Sizong of the Ming dynasty, posthumously known as the Chongzhen Emperor. According to the Ming weight system, the standard weight of a small cash coin was eight fen (approximately 2.864 grams). This coin weighs approximately nine fen, eight li, and nine hao.
The coin adopts the typical square-holed round form characteristic of the Chinese cultural sphere. The obverse bears the inscription “Chongzhen Tongbao” in regular script, arranged from top to bottom and right to left. In the character “禎”, the radical “礻” begins with a dot stroke, a feature known as the “dian-zhen” (dot-style Zhen). In the character “通”, the component “マ” is written as “コ”, forming the so-called “fangtou tong” (square-headed Tong). In the character “寶”, the component “缶” is written as “尔”, producing the variant form “寳”. Below the square hole on the reverse is the character “捌” (eight), which likely serves as a weight mark indicating that the coin was struck to a nominal weight of eight fen, suggesting its circulation in southern regions. The exact mint is unknown; given the chaotic monetary conditions during the late Chongzhen reign, the coin may have been cast in Nanjing, Suzhou-Hangzhou, Hunan-Hubei, or even Yunnan and Guizhou.
In AD 1627 (the seventh year of the Tianqi reign), a peasant named Wang Er launched an uprising in northern Shaanxi, sparking successive rebellions that would continue until the fall of the dynasty. That same year, Hong Taiji initiated the Ning-Jin Campaign, which ultimately failed, though his forces would later repeatedly circumvent the defensive lines to raid the Chinese heartland. Beset by internal rebellion and external threats, the Ming court sharply increased taxation, introducing levies such as the Liao tribute, payment tribute, and training tribute. It also attempted to stabilise currency by reforming minting practices and issuing new coins to finance the military. During the Wanli reign (AD 1573–1620), a wide variety of ancient coins from earlier dynasties, including Tang and Song, circulated alongside new issues. It was not until the Tianqi reign that the government implemented systematic collection and destruction of old coins, replacing them with newly cast currency of markedly inferior quality. Under Chongzhen (AD 1628–1644), the policy of melting down old coins resumed, and the “Chongzhen Tongbao” was issued. Early specimens weighed as much as one qian, three fen (approximately 4.654 grams), or one qian, two fen, five li, with a conversion rate of sixty-five cash to one tael of silver. However, following the Wanli era, as cash coin quality no longer directly affected military morale or official salaries, the southern monetary system grew lax, and rampant private minting caused a devaluation such that three northern coins equalled four southern ones in value, becoming the prevailing exchange norm. In AD 1630 (Chongzhen 3), new regulations stipulated that each northern coin weigh one qian (approx. 3.58 g), and each southern coin eight fen. Officials were dispatched to copper-producing provinces to oversee direct copper extraction and minting, leading to widespread operation of mints. However, minting standards varied across provinces, and illegal casting of inferior coins remained widespread, resulting in a large and complex range of surviving varieties.
The late Ming period coincided with the Little Ice Age, during which a colder climate shifted rainfall zones southward. North China experienced repeated natural disasters, including droughts, floods, and plague. Alongside repeated incursions by the Later Jin (soon to be Qing), these crises contributed to widespread rebellion. The court urgently needed funds for disaster relief, defence, and suppression of unrest. However, entrenched corruption and administrative inertia made it difficult to raise or conserve revenue. Despite several monetary reforms, the results were counterproductive, exacerbating market instability and undermining confidence in the currency. Compounding the crisis was a dramatic contraction in the supply of foreign silver. The Tokugawa shogunate began implementing maritime restrictions from AD 1633 (Chongzhen 6), reducing transshipment of silver. In AD 1639 (Chongzhen 12), the Spanish launched renewed massacres of Chinese merchants in Luzon, interrupting Sino-Spanish trade. In AD 1641 (Chongzhen 14), the Dutch seized Portuguese Malacca, cutting off Macau’s supply of silver. As a result, the silver imported into China plummeted from over three million taels in AD 1640 to just over one million by AD 1642 (Chongzhen 15). Given that the Ming economy had, since the reign of the Wanli Emperor, depended on the Single Whip Reform and the availability of silver, this loss of supply was tantamount to running out of ammunition and provisions.
The Chongzhen Emperor, temple name Ming Sizong and posthumous title Emperor Zhuangliemin, personal name Zhu Youjian, reigned from AD 1627 to 1644, as the sixteenth and final emperor of the Ming dynasty. At the start of his reign, he sought to reform the administration and eliminate the eunuch faction, aiming to revitalise the government. However, the situation was already dire. Popular uprisings led by figures such as Li Zicheng and Zhang Xianzhong intensified, while the Manchu state to the north grew increasingly powerful. Internally, the court was riven by factionalism. The emperor’s suspicious and impetuous temperament led him to constantly dismiss and replace ministers, resulting in inconsistent governance. Financially, the state treasury was nearly depleted, military funding was insufficient, and civil unrest escalated. In AD 1644 (Chongzhen 17), Li Zicheng’s forces captured Beijing, and the emperor hanged himself on Coal Hill. The Ming dynasty thus came to an end. Posterity has viewed the Chongzhen Emperor both as a tragic monarch who died with his state, and as an ineffectual ruler unable to preserve his realm.
