| 正面描述 | Cast brass cash coin with a central square perforation surrounded by four raised Chinese characters in regular script (kaishu), arranged in cruciform reading order: top, bottom, right, left. The legend reads 乾隆通寶 (Qianlong Tongbao), referencing the Qianlong Emperor's reign title and denoting universal currency. The characters are boldly rendered with well-defined strokes against a flat inner field, enclosed within a raised inner rim and a plain outer rim. The coin exhibits a warm brass patina with aged surface texture consistent with period casting. |

The Boo-ji mint (寶濟) operated under the Board of Works in Ji'nan, Shandong, and had a notoriously short run during the early Qianlong period before being shuttered as part of the Qing court's ongoing rationalization of provincial minting. The mint's closure by 1738 means the production window was extremely narrow — likely fewer than three full casting campaigns.
Coins from Boo-ji are scarcer than their Board of Revenue counterparts from the same reign, and examples with clean, unworn cash holes and sharp rim definition are genuinely difficult to source.
