Authorities in New South Wales are cautioning the public to remain vigilant following the discovery of $2,600 in counterfeit currency.

These fake bills have circulated through various businesses in the Hunter Valley area, affecting locations such as Cessnock, Kurri Kurri, Muswellbrook, Scone, Singleton, Blandford, Cliftleigh, Glendon, Merriwa, and Middle Falbrook from May until the present.

Law enforcement is currently conducting an investigation to trace the origin of these counterfeit notes.

Police are advising residents to familiarize themselves with the characteristics of counterfeit money.

Officials stress the importance of checking the texture of the currency, as authentic notes are produced on a distinctive plastic polymer that is notably difficult to tear.

A clear indicator of a counterfeit note includes markings such as “prop” or “specimen” printed on it.

You should also hold the note to the light and look for the Australian coat of arms.

This is generally located to the left of the clear window or denomination numeral when looking at the front of the note.

Another way to tell the difference is to compare the background printing, looking for any distortions or less clearly defined patterns.

Feel for slightly raised printing on the main design of the note and look for the seven-pointed star inside a circle.

Check that the note has a clear window and that it has a clear printed image.

The $50 note has the Southern Cross and the $100 note has the lyrebird.

If possible, look under a UV light to locate the serial numbers.
