1 Cash - Wang Mang (Fifth reform; "Biscut coin"; iron)

During the brief Xin dynasty, the usurper emperor Wang Mang initiated a series of radical currency reforms to centralize economic power and eliminate the traditional Wu Zhu coinage. Issued in 14 CE as part of his fifth and final reform, these coins were part of an ambitious attempt to restructure the Chinese monetary system according to ancient cosmological ideals. The resulting coins, often characterized by their distinctive, uniform, and somewhat minimalist aesthetic, were intended to reflect the order and authority of the state.

This specific iron 'Biscuit' cash coin exemplifies the material scarcity that characterized the latter years of Wang Mang's reign. As economic instability worsened, the minting process shifted toward cheaper, more readily available base metals. The design, noted for its stark utility, was a departure from the intricate inscriptions of earlier periods, serving instead as a blunt instrument of imperial policy. Though the reforms were ultimately unsuccessful and contributed to the dynasty's collapse, these coins remain significant artifacts of a highly experimental period in numismatic history.
