An extremely rare banknote is going under the hammer later this month and is expected to fetch more than £20,000.

The rare £100 note, from the Liverpool branch of the Bank of England, dates back to 1855 and is one of the key lots in an auction of British and Irish banknotes on June 26.

Also included in the auction is another series of notes from Liverpool dating back to 1882.

The £10 notes were signed by the later disgraced Chief Cashier Frank May and are estimated to fetch more than £15,000.

While a £1,000 note dating to 1922, and an incredibly early £10 note dating from 1789 are estimated to fetch around £20,000.

Speaking of the rare £100 note Andrew Pattison, head of the banknotes department at Noonans, the auction house hosting the auction, said: “This remarkable note is of the highest quality and is dated from January 26, 1855, making it almost 170 years old.

“It was signed by Matthew Marshall who was Chief Cashier of the Bank of England between 1835 and 1864 and is one of the highest denominations he signed.

“The note has been cut in half and then taped back together.

“This is because £100 was so much money (around £15,000 today) that the two halves of the note were posted separately for security and then put back together later on so the note could still be used.”
