This is a spade coin (bubi) dating from the late Warring States period, circulated across the realms of the Three Jin and the Two Zhou (the Eastern and Western Zhou domains), encompassing regions corresponding to modern-day Henan and Shanxi provinces. In terms of typological scale, it is classified as a small spade.
The coin is characterised by a flat head, raised shoulders, a flat crotch, square feet, and a straight waist, flaring outwards from the shoulders towards the feet to form a slightly trapezoidal contour, with a raised rim encircling the perimeter. The obverse inscription reads ‘(𡬳阝)shi’. As the character ‘𡬳’ is an archaic variant of ‘受’ (shòu), the legend is also rendered as ‘受阝’ (Shòushi); for commercial convenience within the antiquarian and numismatic collecting market, it is frequently transcribed as ‘授’ (Shòu). Certain scholars propose that ‘𡬳阝’ may be deciphered as ‘泫’ (Xuàn) or ‘端’ (Duān). The reverse is anepigraphic and bounded by a raised rim. Both the obverse and reverse are traversed longitudinally by a central vertical ridge; on the reverse, this median ridge is flanked on either side by an additional lateral line. Since the mid-twentieth century, archaeological specimens of this type have been unearthed across numerous regions, including Beijing, Qi County, Yanggao, and Ruicheng in Shanxi, Baotou and Liangcheng in Inner Mongolia, Lingshou in Hebei, and Zhengzhou in Henan.
In the inaugural year of Duke Lie of Jin (415 BC), Viscount Xian of Zhao fortified the settlement of Xuanshi, marking the historical inception of the toponym Xuanshi. During the Warring States period, strategically positioned at the nexus of the Taihang Route across the Taihang Mountains and the Dan River basin, this locality became a principal focus of military contestation and defensive fortification among the Three Jin states. It was initially held by the state of Han before passing under the dominion of Zhao, whilst certain accounts record intervals of Jin or Wei suzerainty. Towards the late Warring States period, the epochal Battle of Changping—which decisively altered the geopolitical landscape of ancient China—erupted between Qin and Zhao in this vicinity. Following the catastrophic defeat of the Zhao army, the Qin military occupied the entire territory and subsequently established Gaodu County under the jurisdiction of Shangdang Commandery.
The historical genesis of the Three Jin (Han, Zhao, and Wei) lies in the state of Jin, a major power situated along the Fen River basin in Shanxi during the Spring and Autumn period. During the mid-to-late Spring and Autumn period, governance in Jin was progressively usurped by hereditary ministerial aristocratic lineages (qingdafu). Following protracted internal power struggles, the clans of Han, Zhao, and Wei allied in 453 BC to annihilate the rival Zhi clan, precipitating the tripartite partition of the Jin state. They were subsequently granted formal investiture as feudal lords (zhuhou) by the Zhou Son of Heaven—an event commemorated in historiography as the ‘Partition of Jin by the Three Families’ (San Jia Fen Jin)—whilst the reigning Duke of Jin was banished to Duanshi County. Throughout the Warring States period, the Three Jin each occupied distinct territories and pursued divergent paths of statecraft: Han encircled the royal Zhou domain and the Central Plains; Wei pioneered legalist institutional reforms and achieved pre-eminence on both flanks of the Taihang Mountains; and Zhao consolidated its northern frontier defences, instituting the martial policy of adopting nomadic dress and mounted archery (hufu qishe). Although the Three Jin shared common ancestral roots in Jin and adhered to a shared cultural identity centred on the middle reaches of the Yellow River—repeatedly forging vertical alliances (hezong) to counter the eastward encroachment of Qin—persistent territorial disputes and conflicting strategic interests ultimately led to their sequential destruction under Qin military campaigns in the late Warring States period.
Spade money was a form of shovel-shaped metallic currency widely circulated throughout China during the Spring and Autumn and Warring States periods. Deriving its morphology from agricultural implements, it constitutes the earliest cast coinage in China. It circulated primarily within the Zhou royal demesne and the vassal states of Jin, Zheng, Song, and Wei, amongst others. The earliest issues comprised arched-foot and pointed-foot varieties, whereas numismatists generally maintain that the square-foot spade was first developed by the state of Wei before diffusing to neighbouring realms. States such as Yan, Zhao, and Qin also cast spade coins in imitation of Three Jin prototypes, whether to facilitate inter-state commerce or to secure commercial dominance. In comparison with Jin spade coinage, issues from Yan exhibit a deeper waist constriction at the neck and noticeably cruder casting workmanship. Broadly speaking, the evolutionary morphology of spade coins progressed from hollow heads to flat heads; the shoulders narrowed from broad to slender, transitioning from horizontal and raised forms to drooping and rounded profiles; the feet evolved from arched and pointed varieties to square and rounded terminals; the crotches shifted from curved arches to straight-horizontal lines and acute angles; and the coin fabric developed from thick and heavy to light and thin. The prevalence of spade currency probably waned following the conquest of Wei by Qin, finally disappearing with the imperial monetary standardisation enacted by Qin Shi Huang.
