Japanese invasion money: Mickey Mouse pesos, banana dollars, and a shop pile
Japan printed occupation notes for the Philippines, Malaya, Burma, the Indies, and Oceania. Filipinos called them Mickey Mouse money. After liberation most of it was wallpaper. A thick stack is usually a bulk bid, not a fortune.
If the note says The Japanese Government and the picture is banana leaves, that is Japanese invasion money (JIM) — officially Southern Development Bank notes. It is what the Japanese military issued in places they took, or meant to take, in World War II.
It is not an MPC. It is not Allied Military Currency. It is not a US dollar. After the Japanese left, a lot of it was burned in the street. That is the story. The shop story is: most of what walks in is common.
Where it was used
- Philippines — centavos and pesos. Locals called it Mickey Mouse money.
- Malaya / Singapore / Borneo — cents and dollars. Banana money.
- Burma — cents and rupees.
- Netherlands Indies — cents and gulden.
- Oceania — shillings and pounds, printed for New Guinea and nearby islands.
Block letters on the notes matter to specialists. A scarce Oceania or a high-denomination Philippine 500 or 1000 peso can be a real note. A handful of 10-peso banana bills from a cookie tin is not.
What people get wrong
They see “Ten Pesos” and “Japanese Government” and think captured treasure. The Japanese printed these by the ton to replace local cash they had confiscated. After 1945 the notes had no spending power. Collectors still buy them. Common circulated pieces are often a dollar or two each, or a bulk price for the stack.
Reproductions and later tourist reprints exist. If the paper is too white and the ink too bright, say so and we will look. Error-coin hype is the same energy on metal.
What to do
Do not throw the footlocker out. Sleeve the notes. Separate JIM from AMC, from MPCs, from Hawaii notes. We will sort. World coins if the same box has coins.
