Daqian refers to large-denomination cash coins that were produced during the Qing dynasty in China. These coins were manufactured between the years 1853 and 1890 as part of the imperial currency system.
The term Daqian specifically designated cash coins with a denomination of 4 wén or higher. While these large-denomination coins were used during the 19th century, they followed a historical precedent established in earlier Chinese dynasties, where similar types of high-value coinage had faced comparable issues.
