I'm looking into buying general assault badge and wound badge from the pictures. I'm not into medals so I can't tell between older and newer repros, even originals. Could you tell me more about them? Are those old reproductions or newer ones that are aged? Every help is welcome. 

I would honestly do a lot of research beforehand as these items are faked a lot. The other option is to buy from a reputable dealer such as International Military Antiques, The Ruptured Duck, Epic Artifacts, Lakesidetrader, or Wittmann Antique Militaria, you will be paying full market value but you won’t have to worry about getting ripped off and spending money on a counterfeit.
