Brass Pendant

I found the item while digging in my back yard. Many years ago there was a house burned down on the property, so I believe it belonged to the owner of the house. I believe it is made of brass I would say gold but I dont think gold would be tarnished like it is. But it has some sort of soldier's head with a lion head on either side of it. It has a loop on it as if it would be attached to something but if it wadd to hang off of something the picture would be upside down. It also has some sort of dark colored almost like plexi glass backing that wadd held on by a rivet on either side.
