The first flat round coin of Thailand produced from a small manpowered coin production machine which Queen Victoria sent as a royal gift to King Rama IV at the end of 1857. The coins produced from this machine included one Baht, two Salueng, one Salueng and one Fueang coins. This series was called “Rien Bannakarn” (Royal Gift Coins). The coins bear in the obverse the radiating Mongkut mark flanked by a multi-tiered Umbrella of State on the background of branches. The reverse shows the Elephant inside Chakra design. There are stars lining the inner edge on both sides to denote value: one star standing for one Fueang.
