| 背面描述 | Round cast brass reverse centered on the same square perforation and raised square boss. Four legends are disposed in the four quadrants of the field: the Chinese character 當 (dang, 'equal to') to the upper left, the Chinese numeral 十 (shi, 'ten') to the upper right, and Manchu script reading 'Boo-yūn' (the Manchu rendering of the Yunnan Mint name) split to the left and right of the central hole. The characters are rendered in raised relief against a flat field and enclosed by a plain raised rim. Encrustation and casting cracks are visible across the surface. |

The Tongzhi Emperor's reign inherited a mint system severely disrupted by the Panthay Rebellion — a Muslim uprising in Yunnan that controlled much of the province from 1856 until its brutal suppression in 1873. The Yunnan Mint's output during this period was erratic at best, and coins attributable to Boo-yūn (the Manchu mint name for Yunnan) from these years are frequently irregular in fabric and alloy, reflecting the breakdown of centralized supply chains for copper and tin.
Brass rather than the traditional bronze points to wartime improvisation with available metals.
