Very old Silver order Egyptian brooch

Product Name: Very old Silver order Egyptian brooch
Very unique brooch. I am unsure of the age there are not any silver marks. But I have asked people and theh told me that it is sterling Silver. There is a marking on the back that looks like a Y with a period next to it. Someone said that they think that means it was made in Egypt.. There are wings on the bottom of the brooch. The characters depicted may order be God's or goddesses, with male figure wearing a skirt.
