A new polymer £20 note has exchanged hands for £7,500 after going under the hammer during a secret auction on Thursday. The plastic £20, featuring artist JMW Turner, was auctioned off at Spink on 8 April to raise money for three charities, alongside more than 200 other notes, some of which were also among the first to be printed.
The note, which has the serial number AA01 000010, was listed as having a guide price of between £3,000 and £4,000. In total, it sold for 375 times its face value.
The ultra-low-numbered £20 note with a serial number ending in '10' surprised auctioneers after selling for £7,500. Spink and the Bank of England auctioned off new polymer £5 and £10 notes in 2016 and 2017 to raise help money for various charities.
