Police officers express incredulity that shopkeeper accepted forged £20 note featuring two colour photocopies stapled together.
Police have issued a photograph of what could be the worst ever counterfeit banknote.
Officers could hardly believe their eyes when a shopkeeper handed over a fake £20 note comprised of two colour photocopies, loosely attached with staples at the four corners.
The fake note is understood to have been copied on normal printer paper and then cut to size.
As a further clue to its dodgy provenance, the obverse face of the £20 features a distinctive pattern of white lines in a grid formation.
Police officers in Manchester said it was "hard to believe" that anyone would have accepted the forgery.
They declined to name the retailer "to avoid embarassment", but it is believed the note was accepted and the forgers used it to buy undisclosed goods.
Greater Manchester Police said in an official Twitter feed: "Hard to believe that this was accepted as legal currency. Won't name and shame establishment to avoid embarrassment."
It later added: "Not naming premises! It's a reminder for vigilance for all."
A Bank of England spokeswoman said: “Whilst this is a notable exception of a poor quality counterfeit many are more sophisticated, so always check your banknotes.”
