10 Shillings - Elizabeth II Series D, Sir Walter Raleigh, Unissued

This note was designed during a protracted Bank of England review of its entire banknote series but never entered circulation. The Series D programme, which Harry Eccleston drove through from initial design to final approval, took years longer than planned — the ten shilling denomination was ultimately abandoned before issue when the note was demonetised in 1969 and the UK moved toward decimalization, rendering a new ten-shilling note economically pointless before the presses ever ran a public batch.

Surviving examples exist only as proofs or archival specimens. The cancellation of this denomination mid-development makes it one of the more historically clean dead ends in twentieth-century Bank of England printing history.
