| 背面描述 | The reverse presents a largely plain, unadorned convex surface produced by the casting process, with no intentional design elements or inscriptions. The surface exhibits the characteristic luster and irregular texture of cast billon, with natural flow lines and minor surface variations resulting from the molten metal cooling in the mold. A small number of faint incidental marks may be observed, attributable to handling and circulation rather than deliberate stamping. The absence of any official stamps or legends on this side is consistent with standard Edo-period chōgin production practice, where all authentication marks were confined to the obverse. |

The Genbun Chōgin was issued following the Genbun monetary reform of 1736, itself a deliberate debasement ordered by the Tokugawa shogunate to address chronic fiscal shortages — the silver content was slashed from the 80% of the Genroku-era standard down sharply, a policy that generated significant merchant resistance and inflationary pressure throughout the mid-Edo period. The six stamps authenticate both the issuing authority and the alloy grade, each application representing a separate assay or administrative verification by the Ginza.
These bars circulated by weight rather than denomination, making the stamp count a functional record of handling history.
