| 表面の説明 | Cast bronze cash coin featuring a central square perforation surrounded by an inner raised rim. The four-character legend 太定通寶 (Taiding Tongbao) is arranged in the four cardinal positions around the central hole in regular script (kaishu), reading top-to-bottom and right-to-left in the traditional Chinese manner. The characters are rendered in low relief and are heavily worn, consistent with the crude provincial casting style of the Yunnan-Guizhou tribal issues. An outer raised rim encloses the entire field, and the coin exhibits a thick green patina with areas of cuprite, typical of buried bronze cash of this period. |

| 裏面の説明 | Plain reverse with a central square perforation flanked by raised inner and outer rims. The field between the rims is flat and featureless, with no legend, symbols, or mint marks present. The surface is heavily encrusted with a layered green and brown patina, obscuring the original bronze surface. The casting seam and irregular flan edge are characteristic of the primitive sand-casting techniques employed by the Yunnan-Guizhou tribal workshops of the late fifteenth and early sixteenth centuries. |
