I was curious so checked and thought other might be interested. https://www.bankofengland.co.uk/banknotes/counterfeit-banknotes https://www.bankofengland.co.uk/banknotes/counterfeit-bankno... "How many counterfeit banknotes are in circulation? The vast majority of counterfeits are discovered before they go back into circulation, when retailers and the banking system are sorting them. A smaller number are detected by the public or retailers who hand them directly to the police, or when the police carry out search warrants. Counterfeits are typically removed from circulation quickly, often after a single use. Only a small fraction, typically less than 0.02% of banknotes are counterfeit, that is less than 1 in 5,000 banknotes. In the first half of 2020, around 94,000 counterfeit Bank of England banknotes with a face value of £2.1 million were taken out of circulation. At any one time, there is an average of 4 billion genuine banknotes in circulation, with a notional face value of around £75 billion." The scope of the problem seems to be about 2 million pounds per year. I wonder what this solution will save and cost.
