| Reverse description | The reverse is largely plain, featuring a raised square rim around the central square perforation and a raised outer border rim. One or more crescents (lunettes) appear at various positions in the field — above, below, or to the sides of the square hole — serving as mint or workshop marks. The field surrounding the perforation shows the characteristic smooth, unadorned surface typical of Tang dynasty cast cash coinage, with visible casting texture and patination consistent with bronze alloy. |
