| 背面描述 | Two Manchu script words are cast in relief on either side of the central square perforation, read vertically from top to bottom. The right side bears 'Boo' (ᠪᠣᠣ) and the left side 'Dung' (ᡩᡠᠩ), together reading 'Boo-dung,' the Manchu transliteration of the Board of Revenue mint in Beijing. The field is plain and unadorned, enclosed by a raised outer rim, consistent with standard Qing dynasty cash coin reverse typology. |

The Board of Revenue Mint (Hubu) in Beijing was one of two imperial mints operating within the capital during the Daoguang reign, the other being the Board of Works. Both used the "Boo" romanization prefix in their mint signatures — Boo-dung for Revenue, Boo-chiowan for Works — a naming convention that confuses Western collectors more than it should. Production at both mints was chronically disrupted during this reign by copper supply shortages severe enough that the Qing court repeatedly debated suspending cash coinage altogether.
The Daoguang Emperor's reign saw the First Opium War erupt in 1839, straining imperial finances and further degrading mint output in the 1840s. Later pieces in this date range tend to show reduced brass quality as a result.
