| 表面の説明 | Obverse presents the characteristic surface of a cast silver chōgin ingot, displaying a series of pronounced horizontal ridges and undulating furrows across the entire field, produced by the traditional casting and working technique. The roughly oval, elongated form tapers toward rounded ends, with the silver surface exhibiting a naturally mottled, granular texture typical of early Japanese silver currency. No inscriptions, symbols, or die-applied marks are present on this face. |

Yuzuha Chōgin are a distinct subtype of the broader chōgin currency system that operated in Tokugawa Japan, distinguished by their assay marks — the yuzuha stamp indicating authorization under a specific minting administration. Chōgin were produced by the Ginza, the silver monopoly offices established by the Tokugawa shogunate, and circulated by weight rather than face value, making them functionally closer to bullion than to conventional coinage.
The fineness of chōgin was debased multiple times across the Edo period as the shogunate sought revenue through seigniorage — a recurring fiscal pressure that makes die and stamp attribution critical to accurate valuation of any individual piece.
