Ōban 'Tenshō Naga Ōban'

The Tenshō Naga Ōban was produced under the authority of Toyotomi Hideyoshi, who commissioned the Goto family of master goldsmiths to strike these pieces as political instruments rather than everyday currency. They circulated almost exclusively as gifts — distributed to daimyō, military commanders, and foreign dignitaries as demonstrations of Hideyoshi's consolidating power during the final decades of the Sengoku period. Very few entered ordinary commerce.

The elongated format was deliberately oversized to function as a display object. Surviving examples frequently show ink-brushed authentication signatures from Goto craftsmen, applied by hand at the time of issue.
