| Additional information |
The Musashi Sumikaki Koban predates the formal Tokugawa consolidation — it was struck under Tokugawa authority in the Musashi province during the chaotic final years of the Sengoku period, before the Kinza mint system was fully centralized under Edo. The name derives from the ink-brushed assay marks applied directly to the surface by Kinza officials, a verification practice that distinguished early regional issues from later standardized output.
Ieyasu's gold coinage from this transitional moment served explicit political purposes: paying armies and cementing alliances ahead of Sekigahara in 1600. Survivors are rarely found without those authentication marks.
