| 正面描述 | Entirely blank field with a raised encircling rim, characteristic of the gankubi-sen type. The central hole, pierced through the body of a tobacco pipe bowl (gankubi) rather than cast in the conventional manner, is irregular and slightly off-centre in profile. No inscription, device, or decorative element is present on this face. The surface shows a coarse, porous texture consistent with the crude hammering technique employed by unofficial producers. |

| 背面描述 | Entirely blank field lacking any raised rim, distinguishing it from the obverse and confirming the characteristic two-sided asymmetry of gankubi-sen forgeries. The central hole mirrors the irregular, non-square aperture of the obverse, reflecting the pipe-bowl perforation method. The surface is rough and uneven, with no inscription, legend, or decorative motif. The absence of a rim on this face is a defining diagnostic feature of this class of contemporary counterfeit mon coinage. |
