my great grandfathers world war 2 bills

Hi, in my great grandfathers belongings we found these bills from the time serving in world war two. We are not sure of the values and are looking for guidance on valuation and how to sell them. Inquires welcome.

About valuations and selling, these are not my areas, but before selling you must before everything identify the notes you're going to sell. So let's start the identification.

On the first row (without rotating the photo 90º left) we have:
- Austria 100 schilling 1945 (https://en.numista.com/catalogue/note218509.html);
- Austria 10 kroner 1913 (not yet here, what we have here is an overprinted variant, https://en.numista.com/catalogue/note217799.html);
- Germany 50 pfennig 1944 (https://en.numista.com/catalogue/note207250.html);
- A fourth unknown note, too small to recongnize, probably it's face down.

On the second row we have:
- Lots of Germany 1000 mark 1924 (https://en.numista.com/catalogue/note208950.html);
- Belgium 20 francs 1940's (https://en.numista.com/catalogue/note207597.html);
- France 50 francs 1941 (https://en.numista.com/catalogue/note206397.html).

On the third row we have:
- Italy 100 lire 1942-44 (https://en.numista.com/catalogue/note217501.html);
- Germany 1 mark 1944 (https://en.numista.com/catalogue/note205023.html);
- Austria 10 schilling 1944 (https://en.numista.com/catalogue/note218055.html);
- 3x France 2 francs 1944(https://en.numista.com/catalogue/note204612.html).

And on the fourth and last row we have:
- Italy 1000 lire 1940's (https://en.numista.com/catalogue/note217497.html);
- Germany 5 mark 1942 (https://en.numista.com/catalogue/note203783.html);
- Belgium 10 francs 1943 (https://en.numista.com/catalogue/note203940.html).

Thank you so much. What a wonderful start in the community. There is another envelope of bills as well that I will have pictures of tomorrow. I am posting here the picture of the backs as well as a close up of the 10 Kronen variant.

I found the 10 kronen variant: https://colnect.com/en/banknotes/banknote/13619-10_Kronen-1919_Issue-Austria

It is not listed here because our coin and banknote catalogs are a work in progress, we have entered the majority of them but there will always be one or another missing. Think on Wikipedia, our catalog works in a similar way.

And with the zoomed photo I managed to identify that face-down that I couldn't identify before:
Italy 2 lire 1939 (https://en.numista.com/catalogue/note201788.html).

Do any of them have signatures? See link:

Giobruno did a super job identifying the notes for you. Now I suggest you go to ebay completed sales to determine value. For example:
