the eagle in downward flight surrounded by oak leaves is a post-WW2 German paratrooper badge, for wear on the beret I believe. The panzer skull on the white collar tab is in such nice condition, I would suspect it is a reproduction. The WW2 German item third from left on bottom looks to be part of an early SA belt buckle, although I would be suspect of it's authenticity as well
the N.S.D.A.P. pin is a 'tinnie" from the Nuremburg rally, It should be solid bronze. I'd need to see close ups of the front and back to authenticate. If it's real it's got a retail value of around $100 if the pin is still on it
The skull and crossbones (totenkopf) collar tab is from the Hermann Goering Panzer Division of the Luftwaffe, again I'd need to see close ups, but first see if it glows under a black light. All of the ones I found online with the skull were repros...
The round one with the eagle ans swastika is the center badge of an SA belt buckle, again a pic of the back and a close up will help.
Can you post some close up clear shots of the front and back of the ones I circled here as well?
