I'm aware that most if not all of these are german ww2 medals. Are they rare? I dont have any idea on what to do with them. Is there a market for these, should i sell them?
I've edited your pics here:
In red is a Silver Wound Badge.
In yellow are two Eastern Front Medals.
In green is a Naval Artillery War Badge.
Can't identify the others; I think they are civil or political, not military decorations.
Red is an Infantry Assault Badge.
Yellow is another Naval Artillery War Badge.
Green is another Silver Wound Badge.
Blue is a pair of 2nd Class Iron Crosses.
Are they that rare? Is there a market for them?
Yes, if they're real. There's an awful lot of fakes out there - because, yes, there's a hell of a market. Enough copies of Paul Hausser's dagger have been sold the man probably had enough for a whole SS division!
I'd advise asking here. They'll ferret out a fake in no time, and can also spot any mistakes I've made.
Did you have family in the German Army?
