Arizona: Territorial Navajo Police Badge

Old badge marked "ARIZ TERR POLICE NAV. IND.R.".  Worn silvered obverse with applied copper incuse lettered bands.  Reverse has pin soldered to copper surface.  Opinions are all over the place on this one.  Looks old as hell to me, yet the cognoscenti say they've never seen one like it, don't like the pin, etc.  I disagree, but that's my opinion.  Love to see another one.
