Police have again warned of counterfeit cash circulating in the Bendigo area.
In the fake $50 notes, the stars in the clear window have been painted on.
Police say the stars are obvious when looking for them, but it could be easy for them to escape notice when people are making a quick transaction.
Similar counterfeit notes were discovered earlier this year at fast food restaurants.
Counterfeit $50 notes with Chinese characters printed on them have also been found in the past.
Anyone who comes across a counterfeit note is asked to contact Bendigo police station on 5448 1300.
