| 正面铭文 | 新號瑞源 |
| 背面描述 | Completely plain and uninscribed face, featuring a central circular perforation consistent with traditional East Asian cash coinage. The flat field shows no design elements, legends, or decorative motifs, displaying only the natural surface texture of the cast tin with minor flow lines and casting irregularities visible across the flan. A raised inner ring surrounds the central hole, mirroring the structure of the obverse. |

Bangka Island's tin coinage was a direct product of the island's position as one of the world's most productive tin-mining regions, worked intensively under VOC administration and later the Dutch colonial government. These cash pieces circulated primarily among the Chinese mining communities — the kongsi laborers who extracted the ore — and were issued by trading houses rather than a central monetary authority. The Xinhao Ruiyuan designation identifies the issuing merchant firm, not a government mint.
