Japanese forces invaded the Philippines after the bombing of Pearl Harbor. Local currency was demonetized and replaced with notes printed by the Japanese Government, ensuring its absolute power. Denominations were deliberately printed to look like American $1 and $5 bills. Filipinos referred to occupation notes as "Mickey Mouse money" inferring that the currency was play money, thereby worthless. When U.S. forces expelled the Japanese, they also destroyed much of the occupation currency. These surviving Circulated notes are an authentic piece of WWII history!
