This is a small cash coin cast under the reign title of Emperor Shenzong of the Ming dynasty, the Wanli tongbao, first issued in AD 1576, the fourth year of the Wanli reign.
The coin follows the traditional round form with a central square hole typical of the Han cultural sphere. The obverse bears the inscription “Wanli Tongbao,” read from top to bottom and right to left. The right-hand radical of the character tong (通) is written with a smaller “マ”-shaped component, known as xiaotoutong (“small-headed tong”), and its uppermost horizontal stroke is nearly level, known as pingtoutong (“flat-headed tong”); the walking radical (辶) is written with a single dot. The calligraphic style of the inscription matches that of the “Wanli Tongbao” coins bearing the character gong (工) on the reverse. However, as this specimen lacks the gong character, it is referred to as the gongshou (“gong-hand”) type. The gong character may have indicated minting by the Ministry of Works in either Beijing or Nanjing. Above the square hole on the reverse is a small circular mark close to the perforation, known as beixiaori (“small sun on the reverse”).
Coinage of the Wanli tongbao began in AD 1576. The two imperial mints in Beijing and Nanjing produced two grades: “golden-back” coins made from four-fire refined brass, and “lacquered-fire” coins using two-fire brass; provincial mints chiefly struck the type with a milled or “spun” rim. The alloy composition was about 93.8 per cent brass and 6.2 per cent tin. Metallurgical examination of surviving specimens indicates that the so-called “four-fire” and “two-fire” distinctions referred mainly to the surface polish or patina rather than to the intrinsic alloy. Each Wanli tongbao weighed approximately 1.25 qian, and the milled-rim pieces about 1.3 qian. The official Hao Jing memorialised proposing the casting of large-denomination Wanli yuanbao coins valued at ten, thirty, and fifty cash, with reverse legends such as “Illicit Casting a Crime” and “Informers Rewarded” to deter counterfeiting; the proposal was not adopted. However, extant specimens of double-weight coins appear to reflect this unimplemented plan for large issues.
In the early years of Wanli, the coins were well cast and of fine quality, but as military campaigns multiplied and fiscal burdens grew, workmanship deteriorated, the coins became lighter, and private casting proliferated. After the Hongwu reign, the Ming coinage system had gradually simplified, and from the Jiajing period onward almost no large or inscribed reverse types were produced, except for the Jiajing “five-grade” series. During the Wanli era, with the complete collapse of the baochao paper-money system and rapidly increasing state expenditure, numerous new furnaces were opened for accelerated minting. A few rare varieties once again carried reverse characters such as “Hu,” “Gong,” “Gong (public),” “Zheng,” “Tian,” “He,” and “He (crane).”
Another notable feature of the Wanli period was the rise of silver coinage and “mined silver.” With the extensive development of domestic silver mines, coinage in silver became far more frequent than in earlier reigns. Common types include silver Wanli tongbao pieces with the reverse inscription “kuang yin” (“mined silver”), in weights of 0.3, 0.4, and 0.5 tael, as well as larger “Wanli kuangyin” and “Wanli nianzao” varieties. Differences in their workmanship suggest that they were not produced at a single central mint but rather at multiple local or mining mints. By this time, although the government formally maintained its copper-coinage system, silver had become the principal medium of exchange and store of value.
Emperor Shenzong, personal name Zhu Yijun, reigned from AD 1572 to 1620 under the title Wanli and was one of the longest-reigning monarchs of the Ming dynasty. Ascending the throne at the age of ten, his rule spanned the late sixteenth and early seventeenth centuries. In his early years, with Grand Secretary Zhang Juzheng as regent, the government was efficiently administered, the treasury replenished, and the laws strictly enforced—a period known as the “Wanli Restoration.” Zhang Juzheng’s “Single-Whip Reform” simplified taxation and monetised fiscal obligations, briefly restoring prosperity to the Ming finances. After Zhang’s death, however, Wanli took personal control, becoming indecisive and increasingly neglectful of state affairs, refusing audiences for long periods—a situation termed the “Wanli Withdrawal.” He concentrated authority within the inner court and relied heavily on eunuchs, which caused bureaucratic stagnation and constant conflict with officials.
Politically, the reign was dominated by the protracted “Succession Controversy,” in which debate over the designation of the crown prince persisted for more than a decade, undermining imperial authority. Although Wanli eventually appointed Zhu Changluo as heir, his long absence from court contributed indirectly to the “Three Major Cases” that destabilised the central government. In diplomacy and warfare, he ordered the Ming army to assist Korea against the Japanese invasion, dispatching Li Rusong and others to fight in the Imjin War (AD 1592–1598), which successfully repelled Toyotomi Hideyoshi’s forces and preserved the balance of East Asia. He also commanded campaigns to suppress the rebellions of Yang Yinglong in Bozhou and the Ningxia Mutiny, demonstrating some residual military capacity. Yet the prolonged wars consumed immense resources, deepened fiscal strain, and sharply increased the demand for silver, accelerating the emergence of the late-Ming silver economy.
Culturally, the Wanli era witnessed remarkable growth in commerce and urban culture, with a flourishing publishing industry that produced great secular works such as Jin Ping Mei and The Water Margin. Intellectual life became more diverse and critical, while Buddhism, Daoism, and popular cults all prospered, accompanied by widespread temple building. In his later years, Wanli withdrew completely into the palace, absent from audiences for over thirty years. Corruption spread, official discipline decayed, and internal tensions within the Ming state deepened, leaving the dynasty weakened despite the longevity of his reign.
