300 Pounds White, 1807 issue

Bank of England "white notes" of this period were handwritten — or partially so — with cashier signatures applied by hand rather than printed. The £300 denomination was never a workhorse of trade; it existed primarily for large interbank settlements and substantial commercial transactions at a time when the Bank was still operating under the restrictions imposed by the 1797 Suspension Act, which had suspended cash payments in gold and forced the economy to function on paper alone.

Surviving examples from the 1807–1829 run are exceptionally rare. The Bank of England's long-standing practice of cancelling and destroying returned notes means that intact specimens represent near-accidents of preservation.
