| Additional information |
The Board of Works Mint in Beijing was one of two imperial mints operating in the capital during the Xianfeng reign, the other being the Board of Revenue. Both struggled severely during the 1850s as the Taiping Rebellion drained treasury resources and disrupted copper supply chains from Yunnan province. The cash coinage of this period reflects that pressure — alloy compositions grew increasingly inconsistent, and the Boo-gung mint issued across multiple denominations simultaneously in an attempt to offset shortfalls through nominally higher-valued pieces.
The single-cash denomination was the least economically useful of the Xianfeng issues and saw correspondingly low production emphasis relative to the 10-, 50-, and 100-cash coins struck in the same years.
