These fascinating and poorly known coins were struck into the 1800s. They imitated various Dutch, French and British duits used in Indonesia, often very crudely. Imitations of silver dukatons and gold double dukatons are also known. 

Sultanate of Banjar or Banjarmasin was an influential Malay sultanate established in the early 16th century on the southern coast of Borneo (Kalimantan) in present-day Indonesia. It grew as a key trading hub, controlling vital trade routes for pepper, gold, and forest products, and maintaining strong ties with other regional powers, including the Sultanate of Demak and later the Dutch East India Company (VOC). Over time, Dutch influence deepened, and the sultanate became a vassal under Dutch control in the 18th century. After a series of conflicts and weakening autonomy, the sultanate was formally dissolved by the Dutch in 1860, marking the end of its independence and its full incorporation into the Dutch East Indies.
