History
Same design as the Series 4 banknotes, but with the portrait changed to that of His Majesty King Bhumibol Adulyadej (Rama IX).
There are 6 denominations: 50 satang, 1 baht, 5 baht, 10 baht, 20 baht and 100 baht.
Printed by Thomas De La Rue & Company Limited.
Issued gradually beginning in 1948 (B.E. 2491).
Because Series 9 banknotes remained in circulation for more than 20 years, the public became so familiar with the color of each denomination that it was difficult to change. It may therefore be said that the colors of the Series 9 banknotes became the model for the color scheme of banknotes today.
