Obverse description Struck on the convex upper surface of this bullet-form (pot duang) coin, the Dhammachakra (Wheel of the Law) mark is impressed into the silver, displaying eight radiating spokes symbolic of the Eightfold Path. The mark is deeply punched into the rounded field, characteristic of the hand-hammered production technique of the Ayutthaya period. No inscriptions or legends are present; the device alone serves as the royal authenticating stamp.

Reverse description Impressed on the flattened underside of this bullet-form (pot duang) coin, the Ratchawat mark appears as a stylised pyramidal or tiered device composed of a cluster of raised pellets or globules arranged in a triangular configuration, accompanied by a curved linear element. This punch mark served as the royal control mark of the Ayutthaya kingdom, authenticating the coin's denomination and silver content. The surface retains the characteristic irregular, folded texture resulting from the hammering and folding of the silver rod during manufacture.

Additional information

Pod duang coinage of this type circulated throughout the Ayutthaya kingdom for centuries with virtually no design evolution — the deliberately anonymous, bullet-like form made counterfeiting difficult and weight verification straightforward in a market economy built on scales rather than face value. Individual pieces were folded and stamped by hand, meaning no two are dimensionally identical.

The reign attribution to 1680 reflects numismatic convention rather than any marking on the coin itself; Ayutthaya pod duang carried no regal dates. Attribution relies on countermark analysis and hoard provenance.
