正面描述 Cast brass cash coin with a central square perforation, surrounded by four Chinese characters in kaishu (regular script) arranged in cruciform fashion around the hole. The reign title reads top-to-bottom then right-to-left: 乾 (top), 隆 (bottom), 通 (right), 寶 (left), forming the four-character legend 乾隆通寶. The boldly rendered characters are set within a plain, raised square frame bordering the central hole, with a wide, slightly convex outer rim encircling the field. The casting is characteristic of the Qing dynasty imperial mint style, with well-defined strokes and a granular surface texture.

附加信息

The Boo-chuwan mint in Chengdu served the Sichuan interior during Qianlong's reign, a region chronically short of copper and perpetually dependent on brass alloys well after most metropolitan mints had transitioned away from them. Provincial mints like this one operated under Board of Revenue quotas but frequently fell behind, and Sichuan's relative isolation meant local cash often circulated regionally without mixing freely into the broader imperial monetary pool.

Hartill 22.334 places this issue among the more workmanlike provincial outputs of the reign — not a prestige casting.
