1 Cash - Shunzhi Tongbao, Chinese reverse with Yi Li, Yuan

Between 1653 and 1657, the Shunzhi emperor's administration pushed through a series of coinage reforms attempting to standardize cash production across an empire still consolidating control after the Ming collapse. This particular type — carrying the weight denomination in Chinese on the reverse — was part of that experiment, one of several format trials run simultaneously at the Board of Revenue and Board of Works mints in Beijing before the court abandoned the approach entirely by 1657 and shifted to a different reverse convention incorporating Manchu script.
