If you like really old stuff, you will appreciate this piece.  The front side is marked 1837-1897, Victoria Queen and Empress.  The back side is marked Woodiwiss Mayor 1897 Floreat Baton.  Medal is pretty rough hewn, certainly not polished,  very lightweight, and 1.25" in diameter.  I have hand knotted it on 7mm gray pearls.  Necklace is 19" in length and finished with a sterling spring ring closure.
