Batubara was one of several small tin-rich sultanates on Sumatra's northeast coast that issued pitis coinage primarily to facilitate local market trade, where the denomination functioned as petty cash in an economy otherwise dominated by Dutch VOC silver. Sultan Zain al-Abadin Muazzam Shah's reign coincided with a period of intense VOC pressure on Sumatran polities, as the company worked to consolidate pepper and tin trading monopolies across the region.
Tin pitis from minor Sumatran sultanates were notoriously prone to casting irregularities, and surviving examples vary considerably in flan integrity.
