During World War 2, the Bank of England decided to change the colour of the £1 note. Instead of
green, they were printed in blue and pink and for the first time ever included an embedded metal
security thread as extra security against counterfeiters.(B249) They bear the signature of K O Peppiatt.
Until several years ago it was always believed the first prefixes printed were produced at the St Luke’s
Printing Works in London before the bank moved its operations to Overton in Hampshire for the duration
of the war. They were given their own catalogue number. The current catalogue no longer makes this
distinction. We can however now offer the Blue Pink £1 notes with the prefixes which were the first of
each group produced namely A-D, A-E and A-H which used to be referred to as the St Luke’s issues.
Available in 4 grades to meet every pocket.
