1 Cash - Shunzhi Tongbao, Chinese reverse, Yuan

The Yuan-marked cash pieces of the Shunzhi period represent an early experiment in mint identification under the newly established Qing administration. During the 1645–1653 window, both the Board of Revenue and Board of Works mints in Beijing operated simultaneously, and the single Chinese character on the reverse was intended to distinguish output — a practice the Qing court would later systematize far more rigorously with Manchu script. The young Shunzhi Emperor's regime was still consolidating control over a China only partially wrested from the collapsing Ming, and coinage policy reflected that instability.

Brass composition distinguished these issues from the baser alloys common under late Ming production.
