| Reverse description | Cast brass cash coin reverse displaying two Manchu script characters arranged vertically on either side of the central square perforation, identifying the issuing mint. The character ᠪᠣᠣ (Boo) appears to the right of the hole and ᡤᡠᠩ (Gung) to the left, following standard Qing dynasty mint-mark convention. The field is plain and unadorned, bounded by a raised, well-defined outer rim. The casting surface shows the characteristic texture of sand-cast production typical of Qing-era cash coinage. |

| Additional information |
The Board of Revenue Mint at Gongzhou was one of the provincial branches established to relieve pressure on the central Beijing mints during the mid-Qing period. By the Tongzhi reign, output quality across the provincial cash network had deteriorated sharply — decades of fiscal strain from the Taiping Rebellion had degraded both metal supplies and casting discipline. Brass substitution for the standard copper-zinc alloy was widespread by this point, a cost-cutting measure sanctioned from above rather than a local irregularity.
Hartill lists two varieties for this type, distinguished by minor calligraphic differences in the mint name reverse.
