Radiating beams of light emanate from the apex of the central spire, surrounded by elaborate foliate and floral scrollwork filling the field. Small six-pointed stars are interspersed among the decorative elements. The entire design is enclosed within a continuous beaded border running along the inner rim. |

Rama IV — Mongkut — commissioned several pattern coinages in the late 1850s and early 1860s as Thailand negotiated the transition away from bullet money toward Western-style milled coinage. These patterns were almost certainly produced in England, most likely by the Birmingham firm of Pinches or a comparable trade medallist, as the Royal Thai Mint lacked the equipment for such work at the time. White metal was the standard pattern medium for British commercial minters: cheap, workable, and visually distinct from any intended production metal.
The Bowring Treaty of 1855 had opened Siam to foreign trade at scale, making a standardized coinage a practical necessity rather than a symbolic gesture.
