| Additional information |
The Manchu-reverse cash series was introduced in 1653 as part of a broader Qing administrative effort to distinguish imperial coinage from the flood of Ming and rebel-issue cash still circulating across a not-yet-fully-pacified China. Each metropolitan mint received a unique Manchu mint designation — Boo-yuwan identifying the Board of Works facility in Beijing. The experiment was short-lived; by 1661 the Manchu reverses were abandoned in favor of a consolidated single-character system, giving this type a production window of roughly eight years across all issuing mints.
The Board of Works pieces tend to run slightly heavier than their Board of Revenue counterparts from the same period.
