Well aware of the value and significance of Thai coins circulated in the country’s economic system while being virtually historical records that depict the Thai way of living, society, economy, art and culture in each period, the Treasury Department, Ministry of Finance, established the Pavilion of Thai Coins where coins and money of different periods are exhibited. His Majesty King Bhumibol Adulyadej accompanied by Her Majesty the Queen and Their Royal Highnesses Princess Maha Chakri Sirindhorn and Princess Chulabhorn graciously presided over the opening ceremony of the Pavilion of Thai Coins on April 14, 1976. The exhibition of Thai coins continuously expanded to include that of regalia and royal decorations. On display at the Pavilion of Regalia, Royal Decorations and Thai Coins are national treasure items such as royal utensils, emblems of high estate, items used in royal ceremonies, ornaments and the seasonal attire of the Emerald Buddha, among others. Exhibitions on the evolution of Thai coins from Funan Era to the present reign.
The Pavilion of Regalia, Royal Decorations and Thai Coins has met with great success so far. However, given the limited space as well as large numbers of exhibits under conservation which are ready to be put on display, the Treasury Department resolved to expand the coin and currency exhibition by establishing the Coin Museum where the evolution of Thai coins would be exhibited and also to provide a specialized learning center for numismatists, youth and the general public where seminars could be held and knowledge exchanged on the topic of coins and Thai currency.
In trying to locate a suitable site for the Coin Museum, the Treasury Department, Ministry of Finance, settled on the original office building of the Bureau of Monetary Management where public exchange and distribution services of coins in circulation and commemorative coins and medals made by the Treasury Department had been provided. This led to the modification of the building as the Coin Museum.
Money or coins are not only a medium of exchange in the economy but they are also timeless travellers who document the story of humankind across all era.
Vayubhak is the emblem of the Coin Museum, which reflects the Vayubhak emblem stated in Phra Thammanun (Code of Laws) as the emblem of Phraya Rachabhakti, chief of the department overseeing tax collection. It is also used as the emblem of various government units and offices relating to financial institutions.
