It was while Merlyn Lowther was Chief Cashier at the Bank of England that the Bank introduced the Elgar £20. These new notes all had the large portrait of Elizabeth II on the front with a portrait of Edward Elgar on the back alongside Worcester Cathedral where the first performance of his Enigma Variations took place and where today you will find him commemorated in a stained glass window. The very first Elgar £20 notes had the prefix AA01. An important note for all Bank of England collectors.
