1 Mon 'Eirakutsūhō' Hammered gold, reverse Paulownia

The Eirakutsūhō mon was not a Japanese invention — it copied the Yongle Tongbao, a Chinese copper cash coin, and was originally imported from Ming China in vast quantities for use in Japanese trade. By the late Sengoku period, gold versions were being produced in Japan itself, almost certainly under the authority of Toyotomi Hideyoshi, who was consolidating control over the archipelago's gold supply following decades of warlord fragmentation. The paulownia reverse links this piece directly to Hideyoshi, who adopted the kiri crest as his personal mon after receiving it from Emperor Ōgimachi.
