WWII Coins

Here we go again. Just want to thank everyone last night for the help again! I am really learning a lot by posting my friends WWII artifacts.

Here I have some different coins, I am going to try to do the research on them since everyone has been doing it for me!! :) Please correct me when I make a mistake!

PHOTO 1: Top Row: 5 pfennig 1874, 1 pfennig 1911
Second Row: 1930's 1 Reichspfennig
Third Row: 10 Reichspfennig Both 1938
Fourth Row: 1920's & 1930 10 Reichspfennig/Rentenpfennig
Fifth Row: 1 Reichspfennig 1940's?

PHOTO 3: Other European coins please help

PHOTO 4: 1930's &1940's Reichspfennig Coins (How do I know if aluminum or nickel?)

I know nothing about coins, are any rarer than others? Do these have resell value? Thanks everyone!!!!
