The Bank of Thailand has warned the people of its detection of counterfeit 1,000 baht banknotes in circulation but assured they could be easily distinguished by sights and touches. The Central Bank said the counterfeit banknotes it discovered bore the serial numbers of 9ฉA 3828862 and 9ฉA 3828863. They could be easily distinguished as they did not have the watermark of His Majesty the King.
The watermarks of the King on the white space of authentic notes are noticeable on both sides. Their Thai paintings are translucent and their metallic sheens show their denomination numbers. Additionally the denominations on a corner of the bills change their colours when the notes tilt. The Central Bank said authentic banknotes were made from special paper that were hard and durable and tolerated folding and pulling, touching the denomination numbers of genuine notes give the feeling of friction.
