The characters are cast in moderate relief with a plain raised square frame enclosing the aperture. A plain outer rim of uniform width encircles the design. The field surface displays the typical coarse texture associated with sand-cast Qing brass cash coinage. No additional marks or symbols are present in the upper or lower fields. |

| Additional information |
The Jiaqing reign (1796–1820) inherited a mint system already strained by the White Lotus Rebellion, an uprising that drained treasury reserves and disrupted copper supply chains across central China for nearly a decade. The Board of Revenue Mint in Beijing — Boo-jin in Manchu romanization — was among the better-regulated facilities, but even metropolitan output fluctuated considerably as campaign financing competed with routine coinage demands.
Hartill 22.531 represents the standard Board of Revenue issue for this reign, distinguished from Board of Works (Boo-chiowan) pieces by the mint identifier on the reverse. Both facilities operated within the imperial capital simultaneously throughout Jiaqing's tenure.
