The date on the piece (4 Nov 1866) refers to the day when Habsburg/Austria returned the Crown of Lombardy. Here http://en.wikipedia.org/wiki/Third_...Independence is some info about the Austrian-Italian war, without the date though. But see the reference to the Iron Crown near the bottom - in the Italian version http://it.wikipedia.org/wiki/Terza_...#Conseguenze you can read that "Il 4 novembre 1866 I Savoia ebbero consegnata dagli Asburgo la Corona Ferrea (...). So that would be the historic significance, I suppose.
Whether the piece is authentic I don't know. Seems it was intended to be used as a decoration or so, with maybe a name to engraved in the empty area in the center ...
