I have 5 pieces of military currency.
100 yen blue backround, serial #A25465866A, series 100, letter B on it
5 yen light blue backround, serial #A08693411A, series 100 letter B on it
2 pieces that are 1 yen light blue backround, serial#'s A09813495A, A13879992A, series 100 letterB on them
50 Sen light blue backround, serial# A190444430A, series 100 letterB on it

On the back of all of them ISSUED PURSUANT TO MILITARY PROCLAMATION

Just wondering if these are worth anything.
