1 Cash - Shunzhi Tongbao, with circle

The Shunzhi Tongbao series was produced across multiple board mints in Beijing during the earliest years of Qing consolidation, when the dynasty had barely secured the capital and much of the south remained under Ming loyalist or rebel control. The "circle" reverse variant — a plain cast ring rather than a mint name or Manchu character — belongs to the first phase of Shunzhi coinage, lasting barely a year before the Board of Revenue and Board of Works mints began adding distinguishing marks. This makes the series chronologically tight and historically pointed: these coins entered circulation almost simultaneously with the Qing entry into Beijing in 1644.
