| Additional information |
The Board of Revenue operated mints in multiple provincial cities simultaneously during the Yongzheng reign, but Suzhou's facility — known as Boo-su in Manchu mint nomenclature — had a troubled run. The emperor ordered sweeping mint closures across the empire between 1727 and 1730, citing chronic losses from copper shortages and debased output. Suzhou resumed striking only briefly before being shuttered again, which tightly constrains the production window for this type and accounts for its relative scarcity compared to Beijing issues of the same reign.
