200 Cash - Wang Mang Third reform

Wang Mang's monetary reforms were less economic policy than ideological theater — an attempt to legitimize his Xin dynasty by invoking Zhou-era antiquity through archaic coin forms the population hadn't used in centuries. The Third Reform of 10 AD introduced a bewildering array of denominations simultaneously, including this 200-cash piece, as part of a system so complex and internally inconsistent that it collapsed under its own weight within years. Merchants and commoners reportedly continued using Han-era wu zhu coins in defiance of imperial edicts.

Hartill 9.21 is among the more commonly encountered denominations from this reform, though casting quality varies sharply between production centers.
