| Reverse description | Cast reverse displaying a central square hole with inscriptions in two scripts arranged in cruciform layout. Above the hole appears the single Chinese character 當 (Dang, meaning 'equivalent to'), and below appears 十 (Shi, meaning 'ten'), together denoting a value of ten cash. Flanking the hole horizontally are two Manchu script characters reading 'Boo-de' (ᠪᠣᠣ ᡩᡝ), identifying the Board of Revenue Mint in Beijing. The bilingual format in Chinese and Manchu is consistent with standard Qing dynasty mint identification practice. |

| Additional information |
Cast in iron rather than the conventional brass alloy, this issue reflects the Qing dynasty's acute metal shortages during the Taiping Rebellion — a civil war that by 1855 had already killed millions and was draining imperial treasury reserves at a catastrophic rate. The Board of Revenue Mint resorted to iron as an emergency measure, producing coins that contemporaries distrusted and that circulated poorly as a result.
Iron cash from Boo-de are notably prone to oxidation, and uncorroded survivors are genuinely scarce.
