| Obverse description | Impressed into the upper surface of the bullet-form flan, the Prasat (Royal Seal of Rama III) appears as a stylized flame-topped spired tower motif, struck in an oval cartouche. Above the Prasat, a small Unalom device — the sacred spiral symbol — is visible impressed into the rounded dome of the coin, serving as a secondary royal identifier. |

| Reverse description | Impressed into the lower surface of the bullet-form flan, the Unalom (sacred spiral symbol of Rama I) is rendered within a flame-shaped or foliate cartouche, exhibiting the characteristic cursive swirling form associated with the First Reign royal seal. The surrounding field is plain, consistent with the hammered bullet coinage tradition of the Rattanakosin period. |

| Additional information |
Rama III inherited a kingdom still defining its relationship with expanding European colonial powers, and his reign saw deliberate economic consolidation — including tighter control over the bullet coinage that had circulated in Siam for centuries. The Prasat-Chakra-Unalom combination of marks identifies this piece as issued under his authority, punched into the pre-formed silver slug by royal minters at Bangkok.
Bullet coins of this type were produced without dies in the Western sense; the silver was folded and struck into shape, then authenticated with hot punches. Genuine examples carry tool marks consistent with hand production, and no two are identical.
