500 Pounds White

The Bank of England's high-denomination white notes were never intended for ordinary commerce. The £500 was a instrument of inter-bank settlement, used almost exclusively within the clearing system and by merchant banks moving large sums without the friction of coin. Virtually none entered general public circulation, and the Bank's own policy of replacing presented notes with fresh ones means that survivors in any condition are extraordinarily rare — most examples known today came from a handful of estate finds or institutional records.

The series ran across a span of seven decades and two world wars, finally closing in 1943 when wartime restrictions on large-denomination notes tightened. Forgery concerns during the Second World War — particularly after German Operation Bernhard flooded markets with counterfeit £5 notes — accelerated the withdrawal of all high values.
