10 Cash - Zhaowu Tongbao, Seal script

Historical Context: This Zhaowu Tongbao 10 Cash coin, dated 1678, emerges from the tumultuous Rebellion of the Three Feudatories, a critical challenge to the nascent Qing dynasty. Issued by Wu Sangui, proclaimed Emperor of the Great Zhou and adopting the Zhaowu era name, this coinage symbolized his declared imperial legitimacy. Wu Sangui's rebellion (1673-1681) represented a significant internal threat, aiming to restore Han Chinese rule. Currency issuance was a fundamental assertion of sovereignty.

Artistry: The design exemplifies traditional Chinese numismatic artistry, utilizing Seal script (zhuanshu) for the obverse inscription "Zhaowu Tongbao" (昭武通寶). This ancient, formal script choice was deliberate, lending an aura of historical legitimacy and imperial gravitas to Wu Sangui's new regime. While the engraver remains anonymous, execution reflects skilled handwork, rendering complex characters with clarity. The substantial 35mm diameter accommodates the stately script, projecting power and stability for this 10 Cash denomination.

Technical/Grading: Struck in brass, this substantial 35mm, 8.40-gram coin presents specific grading considerations. High-points include the intricate strokes and terminals of the Seal script characters, and the definition of inner and outer rims. A premium example exhibits a strong, even strike, ensuring full legibility of all characters without flatness. Planchet quality, including absence of significant casting flaws or excessive porosity, is crucial. Minimal corrosion, common for brass, is vital to preserve surface details and overall eye appeal.
