The Japanese Pesos are almost worthless, worth a few dollars each. But one point I wanted to share: A lot of it didnt have serial numbers, but some of it did. On ebay, Ive been seeing the 10 peso with serial numbers.
The Japanese Invasion Money for the Philippines for the Philippines with serial numbers that have the number 1 as the first digit in the serial number instead of 0 are replacements. These replacements are common and do not have much of a premium over the other notes of the same series.
Coinage86,you have to be extremely careful with the Japanese occupation notes,as there are some extremely deceptive forgeries,especially of serial numbers being added.I have seen one example of a totally genuine note with a forged serial number (in the right colour too!) that was very deceptive.
