| Obverse description | Impressed into the surface of this bullet-form silver coin is the Prasat (royal throne hall) device, serving as the royal symbol of Rama III and a rebus of his birth name, Prince Thab. The stamp is applied to the convex upper face of the rounded, irregularly shaped planchet characteristic of traditional Thai bullet coinage (Pot Duang). The Prasat motif is rendered in low relief within a small, deeply struck circular impression. |

| Reverse description | The reverse face of this bullet coin bears a struck impression of the Chakra (Wheel of the Law), the dynastic emblem of the Chakri Dynasty, rendered as a circular device surrounded by eight dots arranged equidistantly around its perimeter. The stamp is applied to the convex surface of the compacted silver planchet. The eight-dot Chakra device is characteristic of Rattanakosin-period bullet coinage and serves as a royal validation mark. |

| Additional information |
Bullet coinage of this type — known in Thai as pot duang — was produced by hand, each planchet heated, bent, and punched individually by mint workers. No two are identical in shape. Rama III's reign saw continued reliance on this ancient form despite growing pressure from Western trading partners who found the lumpy, unstamped-looking pieces difficult to authenticate. The Prasat (temple spire) countermark applied to these coins functioned as a guarantee of royal authorization at a time when foreign and debased silver was actively circulating in Bangkok's markets.
