1 Cash - Shunzhi Tongbao, with Yi

The Yi (一) reverse mark on this cash identifies it as an early product of the consolidated metropolitan mints operating under the newly established Qing administration in Beijing — mints that had been seized almost intact from the collapsing Ming. The Shunzhi reign period began in 1644, the same year the Manchu forces entered the capital, and the Board of Revenue and Board of Works moved quickly to assert monetary continuity, retaining Ming minting infrastructure while introducing Qing reign titles.

This specific type, Hartill 22.15, belongs to the very first phase of Qing cash production before the more complex reverse inscription systems were introduced after 1645.
