These are from my grandfathers collection he left when he passed. sorry about the camera i will try to describe them . the first one I beleive is a military note series 1944 number 073164646 it is a 20 mark. the second one i am note sure what it is but i pretty sure it is military curency again. probably japenese. the third is pretty beat up but it is also 10 yen not sure the date. feel free to commment on any and also my crappy camera!!! i have more i will share later. I placed the wrong pic as the back of the first note. i reloaded it but now it is the last one.
Wish I could give you some trivial facts about those notes, but I do want to say thank you for sharing. Hopefully others can tell you more about the notes.
For the first note, goto this website http://aes.iupui.edu/rwise/countries/germany3.html and search for "P-195" and you will see two notes that look just like yours. They are identified as 1944 20 Mark notes. I believe that P-195 is a Pick number and is a reference to a World Paper Money catalog that would have more info on your note including it's value.
Unfortunately I cannot comment on the value or type of notes, but I also appreciate you sharing! It's always good to see photos of items like these that have been passed down! Thanks!
