Thai Baht notes can be found in one, five, ten, twenty, fifty, one hundred, five hundred and one thousand Baht denominations (that I've personally seen). The Baht is very
colorful and shows a
portrait of their
King. The notes are made with
paper or plastic. The 50 Baht notes in particular have plastic versions in heavy
circulation. All Baht notes have a
watermarked portrait of the King to help foil counterfeiters.
Thai coins can be found in several denominations. The smallest coin is about half the size of a US penny, and is called a stang. The smallest denomination I ran across was a 50 stang piece. The stang and the one, five and ten Baht coins feature a portrait of their King. The ten Baht coins feature a brass insert in an aluminum frame, and are very beautifully designed.
In case you haven't noticed the trend, the Thai people are fanatically proud of their monarch. If you visit Thailand and accidently drop a coin or a bill, do NOT stomp on it to keep it from blowing or rolling away. It can be seen as an insult that you are stepping on a portrait of their King, and you will find yourself most unwelcome.
