Fleur de Lis Gold Bar Pin Unisex

Rare piece! Antique gold colored rod with wrapped draping looped around. Center of pin has the gold shield with a red enamel background, featuring a gold fleur-de-lis symbol. There's a lot of writing on the back side, it's not real clear with my magnifying glass, but it does seem to appear that it contains signage to indicate more than what I can decipher. I just think this is ultra cool, it's almost royally secretive!
