60 Pounds White, 1739 issue

Bank of England "white notes" of this period were handwritten documents, not printed banknotes in any modern sense — a cashier inscribed the sum, date, and payee by hand on pre-stamped paper, then signed it. The £60 denomination sits in an odd middle range: too large for ordinary commerce, too small for the merchant wholesale transactions that typically ran in the hundreds. Notes of this value were almost certainly issued to specific individuals against deposit rather than circulating freely.

Survivorship is extreme. Partially used, cancelled, or redeemed notes were routinely destroyed by the Bank. Any that escaped that process — typically through error or private retention — represent the only documentary evidence the denomination existed at all in this run.
