Hawaii overprint note

Modified US bank note used in Hawaii during World War II

A Hawaii overprint note is one of a series of banknotes issued during World War II as an emergency issue after the attack on Pearl Harbor. The intent of the overprints was to easily distinguish United States dollars captured by the Imperial Japanese Armed Forces in the event of an invasion of Hawaii and render the notes worthless. Although a sizeable number of the notes were recalled and destroyed after the end of World War II, many escaped destruction and exist as collectibles of numismatic interest in the present day.
