Newbie German Stamp Question
I have a friend whose 80 something father passed away who inherited a bunch (hundreds) of German stamps from the 1920's through 1940's from his father (friends grandfather). Father and Grandfather were born and lived in Germany. Anyway, many have not been postmarked ie unused and have Hitler, swastika, golden eagles, and general German stuff from that era. My question is it legal to have possession of this stuff and is it worth anything?
