50 Rupees

Ceylon's wartime currency operated under an unusual administrative split: the island remained under the India Office until 1948, but its note-issuing function was handled by the Government of Ceylon directly rather than through any reserve bank structure. The 50 Rupees denomination was the highest value in general circulation during this period, issued against a backdrop of acute wartime inflation pressure and the Japanese naval threat that culminated in the April 1942 Colombo raid.

Thomas De La Rue continued printing in London throughout the war years despite Blitz disruption — a logistical feat that often goes unacknowledged. The P#37 series spans 1941–1945 without mid-series design modification, making date attribution essential for precise catalog placement.
