More than $200 million in US currency was burned at both a crematorium and the Aiea Sugar Mill in Hawaii, due to being redeemed for HAWAII Overprint Notes – 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 US currency captured by Japanese forces in the event of an invasion of Hawaii and render the bills useless.
