At the time of Japanese invasion, stocks of dollar notes were still held in treasury vaults in Singapore and Penang. When Penang was evacuated in December 1941, 600,000 one-dollar notes and 100,000 five-dollar notes were abandoned in the treasury, where they fell into the hands of the Japanese. In Singapore, 4,200,000 one-dollar and 1,000,000 five-dollar notes were destroyed, and 21,000,000 one-dollar notes and 3,900,000 five-dollar notes shipped to India for safety. When British forces reoccupied Singapore in September 1945, they found all the abandoned notes of this series, except for a bundle of one thousand dollar notes captured in Penang, in the vaults of the Japanese sub-treasury.
