Thonburi and Rattanakosin photduang The Thonburi period (1767–1782) and the Rattanakosin period, beginning in 1782, adopted the photduang design from the late Ayutthaya period. The coins from these periods had no central hole, and the legs were even shorter. A key difference was that Thonburi photduang lacked the elliptical nick, whereas the Rattanakosin coins reintroduced this feature, similar to the Ayutthaya coins. Photduang from these later periods typically featured two stamped marks: the dynasty mark on top and the king's personal mark on the front part. The dynasty mark often symbolized the kingdom's ruling dynasty, while the king's personal mark represented the reigning monarch.
