| 裏面の説明 | Completely plain and uniface, with no legends, symbols, or decorative devices of any kind. The central square perforation is framed by a raised inner rim, with a similarly plain raised outer rim encircling the flat, featureless field. The surface displays the same blue-green patination visible on the obverse, consistent with the coin's cast copper composition and age. |

Khai Thái was the reign era of Trần Minh Tông, the fifth emperor of the Trần dynasty, whose court maintained strict Confucian administrative structures borrowed heavily from Song Chinese precedent — including the practice of issuing new cash coinage to mark each reign period. The clerical script designation here distinguishes this emission from parallel issues in standard script, a distinction the Trần court made deliberately to differentiate administrative and ceremonial contexts.
Barker's attribution to this narrow five-year window relies on reign-era correlation rather than mint documentation, as Vietnamese cash of this period carry no mint marks.
