Fraudsters have been trying to scam honest shopkeepers with fake “twenty poond” notes.
Police have warned businesses to be vigilant after a spate of reports of phoney £20 notes.
Cops in Bodmin, Cornwall, said a number of counterfeit notes were used in the town.
The fake cash has one big giveaway – as the word pound is spelt poond.
And the old-style note is actually toy money used in movies and TV, police said.
But that hasn’t stopped dishonest con artists trying to use them in shops and takeaways.
A police statement read: “We've received reports of individuals using or attempting to use these 'Twenty Poond' notes in shops and takeaways.
“As you can see from the attached photos, these notes are clearly fake. They are all exactly the same, with the same serial number and wording identifying it as 'toy' money.
“There are also several other discrepancies and they also feel like paper and not proper money."
“We ask shopkeepers to remain vigilant when accepting notes.”
The fake scores have identical serial numbers and are printed with the words: “This is not legal. It is to be used for motion props”
Some social media users were less than forgiving towards workers who had been caught out by the scam.
One person said: “If you get scammed with this, you deserve it.”
Another wrote: “It's clever really if handed face up they look legit and says a toy on other side and probably totally legal to print them but becomes illegal when you try to sell them for other uses or spend them."
Head of Action Fraud, Pauline Smith told Lad Bible: "Criminals are using increasingly sophisticated networks and methods to make counterfeit notes and coins.
"If you have been passed or recover counterfeit currency, this should be reported to your local police force.”
