Murrumbidgee Police District is urging everyone to check their cash after one Griffith supermarket was duped.
It is alleged the fake note was handed forward in a stack of notes as a form of disguise.
On closer inspection, the note was missing the clear window, and was of poorer quality.
Chief Inspector John Wadsworth said it was a "timely reminder" for everyone to be on the lookout for fake money.
"While it predominantly appeared to be genuine, looking closer it was counterfeit," he said.
Things to look out for when identifying the real money from fake counterparts:
- What is it made out of? Australian banknotes are printed on plastic and have a distinct feel. If a banknote feels excessively thick or thin compared to a genuine banknote, it is most likely a counterfeit. It is difficult to tear along the edge of a genuine banknote. A genuine banknote should spring back if you scrunch it up.
- Look for the coat of arms: If you hold the banknote to the light, you should see the Australian Coat of Arms.
- Look for the star: there are diamond-shaped patterns printed on the inside of the circle on both sides of the banknote. If you hold the banknote up to the light, the patterns should line up perfectly to form a seven-pointed star.
- Check the clear window: The clear window will be an integral part of the banknote, not an addition. Check that the white image printed on the window cannot be easily rubbed off.
- Embossing: there is a wave pattern in the window of the $10 banknote, and the value of the banknote in the windows of $20, $50 and $100 banknotes.
