5 Pounds

Cyprus was still a Crown Colony when this series was issued, and the Government of Cyprus — not a central bank — served as the direct note-issuing authority, a arrangement reflecting the colonial administration's tight grip on monetary affairs. De La Rue's printing is characteristically fine for the period, but the real curiosity here is the issuer itself: formal central banking wouldn't arrive in Cyprus until 1963.

The six-year date range suggests notes were signed and dated individually upon issue rather than printed in discrete dated runs — worth examining closely on any example.
