I found some currency that my dad brought home from WWII and possibly Korea. I am curious as to what they are worth and where I can go to find out. One is a 1 pound note from the Reserve Bank of New Zealand,a one dollar bank of Canada bill, Military currency: one yen, ten yen and 50 yen, Japanese Government fifty centavos and one centavo and a Japanese bill that just shows $50 and Japanese writing.
