Enligt en artikel i Bangkok Post och även på forumet ThaiVisa så är det ganska många falska 1000-bath sedlar i omlopp.

"Fake banknotes flood city as recession grips
Warning to be alert over festive period
Bangkok: -- Thousands of counterfeit banknotes, particularly 1,000-baht bills, are likely to go into circulation over the New Year period, the Bank of Thailand (BoT) warned yesterday.
Nopporn Pramojaney, the BoT's assistant governor for note-printing, warned consumers and businesses to watch out for odd-looking notes during the holiday season.
He said counterfeit notes in circulation increased by 80% this year, possibly as a consequence of hard economic times.
In the 12 months to the end of November, the BoT had confiscated 18,895 fake notes - compared with 10,819 notes seized in the same period last year. Most fake notes were 1,000-baht bills, which accounted for 61% of seized notes.
Mr Nopporn said that for every one million banknotes in circulation, up to 7,000 of those would be fakes.
More counterfeit notes were expected to enter circulation next year due to the economic recession.
Pol Lt-Gen Danaithorn Wongthai, chief of the Office of Police Forensic Science has given some tips for the public to differentiate real banknotes from fake ones.
A real banknote bears the watermark of His Majesty the King, which can only be seen when it is held up to the light. The picture of the King, the letters and the digits showing the value on the real note have an embossed feel.
Notes of 1,000-baht, 500-baht and 100-baht value have reflective and holographic metallic strips.
Police Region 1 recently arrested four people including a former school director, for banknote forgery, and seized 203 fake 1,000-baht notes.
Police also confiscated three compressed bricks of marijuana weighing 3kg from the suspects.
Pol Lt-Gen Chalong Sonjai, Police Region 1 commissioner, said the suspects used the fake notes to pay for drugs they bought in Laos.
In Phuket, police arrested three people and seized three fake 1,000-baht notes in Thalang district on Wednesday.
Pol Col Thammanoon Faiju, superintendent of Thalang police station, said forged bills were often used at nightspots, petrol stations or grocery stores popular with the elderly.
