1 Bu 'Kaga Nanryōgin' Cursive script

Kaga Domain's silver bu issues of 1866 occupy an awkward moment in Japanese monetary history — the Tokugawa shogunate was actively debasing its own national coinage while individual domains scrambled to maintain workable local exchange media. The "Nanryōgin" designation links this piece to the older nanbansen silver weight standard, invoked here more as a mark of quality assurance than any formal institutional connection.

The cursive script variety is distinguished from the standard issue by its calligraphic execution, likely reflecting a different engraver or authorization batch. Within two years of this striking, the Meiji Restoration would abolish domain coinage entirely.
