| 背面描述 | Central square hole flanked by two Manchu characters denoting the mint name 'Boo-chuwan' (ᠪᠣᠣ ᠴᡠᠸᠠᠨ), referencing the Board of Revenue Mint at Chengdu (Sichuan). The characters appear to the left and right of the square perforation in the customary arrangement for Qing cash coinage. Relief is weak and definition poor, reflecting the crude casting quality characteristic of a privately produced imitation. The plain, undecorated field and irregular rim further attest to non-official manufacture. |

Privately cast cash coins from the Chengdu mint's orbit represent a persistent headache for Qing monetary administrators throughout the Daoguang period (1821–1850). The imperial government repeatedly issued edicts against private casting, particularly in Sichuan, where geographic isolation from Beijing made enforcement inconsistent at best. Boo-chuwan pieces — struck under the Board of Revenue's Chengdu facility — were frequently imitated by local workshops exploiting the province's copper supply and distance from central oversight.
The brass composition here, rather than the standard bronze alloy, is often the clearest indicator of private origin.
