| 裏面の説明 | Plain and uninscribed uniface reverse, entirely devoid of design or legend. The surface is flat with a raised square inner rim surrounding the central square perforation and a plain outer rim, displaying a uniform olive-green patina with scattered green cuprite deposits throughout the field, typical of ancient Chinese cast bronze cash coins of the Xin dynasty period. |

Wang Mang's currency reforms are among the most aggressively interventionist monetary experiments in Chinese history. The second reform, launched in 9 AD upon the establishment of the Xin dynasty, introduced a bewildering array of denominations — at one point numbering twenty-eight distinct coin types — as Mang attempted to fund his administration while simultaneously dismantling the economic infrastructure of the displaced Han. The 30-cash valuation assigned to this piece bore essentially no relationship to its metal content, a gap that drove immediate counterfeiting and widespread non-compliance.
By 14 AD the entire system had collapsed into a simplified replacement, making the active emission window for this denomination under five years.
