I have a German penny from 1943. It's probably worth... Well... a penny.It's got an eagle bearing a swastika on the front.
I would buy that for like $100 man.
Really, I have quite a few national socialist-era coins
So German coins are expensive? Cool. I don't want any national socialist/Swastika ones though.
I heard a Deutsche mark is about 1/2 Euro. But it may rise in value since it is an outdated currency.
