| 背面描述 | The reverse displays two Manchu script characters in raised relief, one on each side of the central square hole, reading vertically: ᠪᠣᠣ (Boo) to the right and ᠰᡠ (Su) to the left, together forming the mint name Boo-su, identifying the Suzhou Mint. The characters are cleanly cast in a bold style typical of Qing dynasty cash coinage, set against a plain, flat field. The square central perforation is well-defined with neat inner edges, and the coin rim is raised and even. |

The Xianfeng reign coincided with the Taiping Rebellion, one of the deadliest civil wars in recorded history, which severely disrupted copper supply chains and forced both the Board of Revenue and Board of Works mints in Beijing to experiment with alloy compositions and flan sizes throughout the 1850s. The "large type" designation distinguishes this issue from the reduced-weight cash pieces that appeared as the fiscal strain deepened — by the later Xianfeng years, coin quality had deteriorated dramatically across nearly all provincial and metropolitan mints.
Boo-su is the Manchu rendering of the Board of Revenue mint. Hartill 22.923 places this among the heavier, better-produced early Xianfeng issues before wartime economics took hold.
