| 正面描述 | Mexican republican eagle displayed facing left, perched upon a prickly pear cactus growing from a rocky outcrop, with a serpent grasped in its beak, wings outstretched in heraldic fashion. The central device is flanked by a wreath composed of oak branches on the left and laurel on the right. The circumferential legend REPUBLICA MEXICANA arcs across the upper field, contained within a toothed or beaded border. The overall design follows the established Mexican republican coinage style of the mid-nineteenth century. |

When Japan was forced open to foreign trade by the Convention of Kanagawa in 1854, the Shogunate faced an immediate arbitrage crisis: Western merchants recognized that silver was undervalued relative to gold in Japan and began draining the country's gold reserves at a catastrophic rate. As a stopgap, the government countermarked foreign silver — primarily Mexican and other Spanish-colonial 8 reales pieces — with two oval punches certifying their acceptance at a fixed rate of 3 bu, roughly three-quarters of a Mexican dollar's face equivalent.
The arrangement lasted only a few years before the Shogunate was forced into deeper monetary reforms. Countermarked pieces were withdrawn as dedicated trade coinage replaced them, making circulated survivors with both punches intact considerably harder to locate than the raw host coins themselves.
