Historical Context: The 1 Cash Daoguang Tongbao, Boo-san, dates to Emperor Daoguang's reign (1821-1850), a pivotal era of accelerating Qing Dynasty decline. This period saw significant internal unrest and external pressures, including the First Opium War (1839-1842), often leading to variable coinage quality and weight. The "Boo-san" (寶泉) inscription identifies the Board of Revenue mint in Beijing, a central facility producing vast quantities of essential circulating treasures for daily commerce.
Artistry: This coin exemplifies the traditional Chinese calligraphic aesthetic, prioritizing clarity and balance of its inscribed characters. Individual engravers are not typically recorded for these mass-produced cast issues; instead, the artistry reflects standardized imperial script and the skill of master die carvers. The obverse features "Daoguang Tongbao" (道光通寶) in regular script, while the reverse displays the Manchu "Boo-san" (寶泉), denoting the mint of origin and underscoring Qing's dual linguistic heritage.
Technical/Grading: Optimal preservation for this cast brass 1 Cash coin is marked by sharp definition of the four obverse "Daoguang Tongbao" characters and the two reverse Manchu "Boo-san" characters, especially their inner strokes. Key grading high-points include crispness of both inner and outer rims, often weak or irregular from casting. A well-defined central square hole, free from significant casting flash, and a smooth planchet surface without excessive pitting or major flaws, are critical indicators of quality.
