| 背面描述 | Plain, uniface reverse with no design, inscription, or decorative elements. The surface exhibits the coarse, pitted texture characteristic of roughly cast tin, with flow lines and minor casting flaws visible across the field. A central square hole mirrors that of the obverse, consistent with the traditional East Asian cash coin format used for this Bangka Island emergency issue. |

Bangka Island's tin coinage emerged directly from the island's dominant industry — by the late eighteenth century, Bangka was among the most productive tin-mining territories in Southeast Asia, with the Dutch VOC and later the Batavian Republic extracting enormous quantities of the metal. Striking coins from locally smelted tin was a practical consequence of that abundance, not a monetary innovation.
The Jida series were produced under Chinese mining kongsi administration, the labor syndicates that effectively ran Bangka's interior operations. "Jida" itself references these kongsi structures.
