What Type of Currency?
This looks like the strangest currency to have ever existed. Taking a close look at the currency, it appears to be a mock-up design of some sort for monopoly or another money board game. There are a number of things that look strange about those bills. For one, it is Pesos that was seemingly issued by the Japanese government.
The official currency of Japan is Yen. There are eight countries that use Pesos, and Japan isn’t one of them. Also, the words on the money is written in English, and not Japanese. The internet had an answer for the mystery, as the currency was identified to be valid, but irrelevant. It was in circulation around 1941 when Japan occupied the Philippines.
