An Aussie travelling through Thailand has discovered his money was practically worthless thanks to a tiny detail. While rips and tears can sometimes reduce the value of notes, a mark meant to verify legitimate notes could have been to blame for the awkward situation.

Peter Fuller was left scratching his head when he tried to get some local currency on his trip. He asked people on social media if they knew why he was knocked back.

"Went to exchange AUS currency for Thai baht in Thailand and they rejected this note because of this little blue stamp, anyone got any idea why?" he said on Facebook.

Thailand has very strict rules on the type of currency it accepts, according to Wise, and it will turn away any notes that have been "defaced" or "damaged". Travellers have been warned to bring only "crisp" and "clean" notes if they want to get them exchanged for local currency.

In this case, the teller at the currency exchange might have looked at the blue stamp as being defaced and rejected it.

This has stung other travellers in the past, with people posting online how they had notes knocked back because of random markings you'd normally not even notice.
