This is a bronze coin known as the “Cao Wei Wu Zhu,” minted from the first year of Taihe to the second year of Xianxi (AD 227–265) under the successive emperors of the Cao Wei regime following Emperor Ming.
The obverse bears the inscription “Five Zhu” in small seal script, read from right to left. The strokes of the character “Five” extend to and connect with the outer rim of the coin, a feature referred to in numismatics as “linked rim” (lianlun). The strokes of the character “Zhu” are pressed against by the outer rim, a phenomenon known as “compressed metal” (yajin). Some contemporary scholars regard “compressed metal” as a diagnostic feature of Five-Zhu coins minted during the Cao Wei period. The character “Five” is composed of curved strokes, while the “zhu” component of the character “Zhu” begins with a rounded turning stroke. The coin exhibits an outer rim on both obverse and reverse, but no inner border on the obverse. Below the central hole on the obverse are four raised vertical lines, while above the hole on the reverse is a single raised dot, a feature known as “one star above the hole” (chuan shang yi xing). Multiple raised vertical lines, appearing either on the obverse or reverse, have been commonly observed since the mid-Eastern Han period. Their continued use on Wei-dynasty Five-Zhu coins suggests a legacy of earlier coinage traditions, although the specific reason for their inclusion remains to be determined.
The Book of Jin (Jin Shu晉書), in its Treatise on Food and Money (Shihuo Zhi食貨志), states: “When Cao Cao became Chancellor, he abolished it and reinstated the Wu Zhu coin.” This refers to Cao Cao’s decree, after assuming the position of Chancellor in AD 208, to ban the small, inscription-less coins issued by Dong Zhuo and to reinstate the standard Wu Zhu coin format used since the Han dynasty as the sole legal currency. However, no official Wu Zhu coins were minted at the time. It was not until the first year of Emperor Ming’s Taihe reign (AD 227) that official minting resumed, as indicated by the phrase “new Wu Zhu coins were minted” (geng zhu wu zhu qian 更鑄五銖錢). Based on excavated tombs, it appears that during the Cao Wei period, private coin minting was permitted alongside state-issued currency. After the Western Jin replaced the Wei in AD 266, no new official coins were minted throughout the Jin dynasty until the seventh year of Yuanjia (AD 430) under the Liu Song dynasty. Instead, Han and Wei-era copper coins continued to circulate. The allowance of private minting under the Cao Wei and Jin dynasties may have been a pragmatic response to the entrenched power of aristocratic clans, whose control over private minting was difficult to reclaim due to the significant profits involved. Alternatively, it may reflect the collapse of the monetary economy since the later Eastern Han period, which resulted in greater reliance on a barter-based economy.
