Unbranded Antique Mother of Pearl Star of Bethlehem Made in Bethlehem & 7 Point Star Pins

Antique Mother of Pearl Star of Bethlehem Made in Bethlehem & 7 Point Star Collectible Pins. Pre-owned, these pins are in excellent condition. The only wear is on the hook clasps on the back. There is a mark on the 7-point star pin, but I don't know what it is. 19
