People find crap like that all over the place metal detecting. Obviously not with the nazi insignia usually unless you are in Germany but stuff like old coins, buckles, pins etc. Sometimes once in a while someone uncovers something really old but tbh if you go dig in a back garden in Europe you'll find older crap than this.

It's technically historical in that it was around a long time ago but it doesn't add anything to our historical knowledge and is worth jack shit except to dumb nazis I guess.
