Paul- it?s Latin for To each his own. It was the motto of the order of the black eagle - of which this appears to be a badge of the order. Whether it?s real or not the medal guys will know, but I would guess it may be police related or predate ww2. I know the ss translated the motto to German- it was Jedem das Seine and was on the buchenwald gate. Other than that o don?t know anything else about it.
