As with many other currencies, the baht has a mixture of coins and banknotes in circulation. One baht consists of 100 satang, though the value of satang is so low that you’re unlikely to come across a satang coin during your stay.
There are six coin denominations in circulation, made up of the rare 25 satang and 50 satang, as well as the more common 1 baht, 2 baht, 5 baht, and 10 baht.
Thai banknotes come in five denominations of 20 baht, 50 baht, 100 baht, 500 baht, and 1000 baht. Thai bills feature portraits of the royal family and are colour coded.
Familiarise yourself with the 10 baht coin and the red 100 baht banknote; they’re the most common denominations in use.
