| 背面描述 | Plain reverse field surrounding the central square perforation, devoid of any inscriptions, symbols, or decorative elements. The surface exhibits the characteristic granular texture and slight irregularities consistent with Ming dynasty sand-casting technology. A faint raised inner rim borders the square hole, and a plain outer rim defines the coin's periphery. On some mint varieties, a single Chinese character mint mark may appear, but this example shows a blank reverse. |

| 附加信息 |
The Wanli reign (1572–1620) is one of the most documented in Ming numismatic history, in part because the period saw chronic shortfalls in copper supply that forced the Board of Revenue to repeatedly suspend and restart cash production. Wanli himself was famously disengaged from governance for stretches exceeding a decade, and the resulting administrative vacuum created inconsistencies across mint outputs — weight standards drifted, and alloy compositions varied considerably between provincial facilities.
Hartill 20.140 represents one of the more common attributions within the Wanli series, though distinguishing mint origins without provenance documentation remains genuinely difficult.
