1 Cash - Heshun Kongsi republics

The Heshun Kongsi — formally the Lanfang Republic by some accounts, though the federation structure was considerably more complex than that label suggests — was a Chinese mining cooperative turned self-governing polity in western Borneo, operating the gold fields around Mandor. These tin cash pieces functioned as internal trade currency among the Hakka miners who effectively ran their own taxation, judiciary, and militia entirely outside Dutch colonial authority. The Dutch eventually dismantled the federation in 1884, three decades after this type's issue ended.
