10 Shillings Postal Order

British Postal Orders occupy an odd corner of notaphily — they are not banknotes, not cheques, and not stamps, but they have been collected seriously since the late Victorian period. The Post Office Savings Bank and the postal order system together formed a parallel payments infrastructure for people without bank accounts, and the 10 Shilling denomination was the workhorse of that system through the postwar decade.

By 1957 the design had been largely stable for years, printed by Waterlow & Sons under contract. Postal orders were not meant to survive — payees were expected to cash them promptly, and uncashed examples were cancelled and returned to the issuing office. Survivors in unencashed condition are genuinely uncommon for this reason, not because of small print runs.
