Pavilion of Regalia, Royal Decorations and Coins
The Pavilion of Regalia, Royal Decorations and Coins is a museum showcasing regalia, royal Thai decorations of the early period, historical Thai money and ornaments used in the royal courts. It is under the supervision of the Bureau of Grand National Treasure, the Treasury Department which has the responsibility to safeguard, conserve, and display national treasures. The museum is inside the Royal Grand Palace, at the entrance to the Emerald Buddha Temple. History
In 1976, the museum was originally called "The Coins Pavilion" and was established by the Treasury Department to display the evolution of Thai coins. The museum was inaugurated on 14 April 1976, presided over by the king and queen, Princess Maha Chakri Sirindhorn and Princess Chulabhorn. In 1978, the Treasury Department expanded the scope of the collection to include royal regalia and decorations and was renamed "The Royal Regalia, Decorations and Coins Pavilion". The expanded collection was opened on 11 August 1978 and once again presided over by the king and queen, Princess Maha Chakri Sirindhorn, and Princess Chulabhorn. In 1992, after almost two decades and over half a million visitors a year, the need to renovate the museum was apparent. A new interior, a new design, refurbished rooms, and more selective displays were required along with a need to focus on preservation as well as the security of the museum. Once renovations were completed a new name was chosen, "The Pavilion of Regalia, Royal Decorations and Coins". In 2002, the restructuring of the Treasury Department created a new office, "The Bureau of Grand National Treasure". Its primary purpose is to conserve as well as display the items housed by the museum. Since the establishment of this new government department on 3 October 2002, museum has been managed by the Bureau of Grand National Treasure. Exhibition rooms

It starts with the round flat coins of Funan and Dvaravati Kingdoms which occupied areas which are now parts of Thailand. When Sukhothai Kingdom was founded in 1238, the money called Pod Duang or 'bullet money' was created. The money was mostly made of silver. It was round-shaped and rolled into inwardly curving legs with pointed ends. Pod Duang was used as currency of Thailand for more than 700 years before it was replaced by modern coins. The display also shows a large collection of coins produced during the Bangkok period. The highlight of which include "Royal Gift" coins which were minted from a small coin production machine sent to King Rama IV as a royal gift from Queen Victoria in 1857.
