| 正面铭文 | 攵 寶 永 久 (Translation: Eternal money of the Bunkyū Era) |
| 背面描述 | The reverse displays eleven wave or scale-like (nami) decorative motifs arranged in concentric arched rows radiating outward from the central square hole toward the coin's rim, a design distinctive of the 4 Mon Bunkyūeihō series. The deeply incised, layered wave pattern is cast in bold relief, filling the entire field. This elaborate reverse decoration was used as an anti-counterfeiting measure. The image shown appears to display this side of the coin. |

The Chōkaku mint — a private operation licensed under the domain system — was one of several regional producers authorized to strike Bunkyū-era cash coins as the Tokugawa government struggled to meet demand for low-denomination currency in its final years. Tin alloy issues from this period were emergency expedients; copper shortages driven by export pressure and the opening of treaty ports after 1858 forced mints to experiment with inferior metals. These tin pieces circulated poorly and were unpopular, which counterintuitively means many were hoarded rather than spent.
