The imagery balances Thai cultural identity—represented by the prominent Phra Samut Chedi temple on the obverse—with institutional authority symbolized by the classical government building on the reverse. The English printer credit to Thomas de la Rue & Company reflects Thailand's reliance on British security printing expertise during this formative period of the modern Thai state.

Below is an detailed architectural illustration of Phra Samut Chedi temple complex, characterized by multiple pointed spires typical of Thai Buddhist architecture, framed by intricate guilloche border patterns. The reverse displays a neoclassical domed capitol-style building with columned portico, flanked by decorative palm fronds in the upper corners. A large circular watermark area occupies the left side. Both sides feature fine-line engraving throughout with geometric scrollwork in the decorative borders.
