Introduction :

     "Pod Duang Money" was made from bars of silver bent or folded and hammered into shape stamped with the mark of the ruler.

     Standardized Pod Duang money was used during the Sukhothai , Ayutthaya,Thon Buri and Rattanakosin periods. In the reign of King Mongkut, the country was opened for commerce and trade with the West. Because of the increasing demand for currency in circulation due to the rapid expansion of foreign trade, King Mongkut ordered the modern machines to mint flat coins instead of Pod Duang. From that point until the present day, coins became part of monetary system of Thailand.
