Antique Mother of Pearl Buttons MOP Shell 1 1/2 Set of 3

This is a set of three mother of pearl buttons, each measuring 1 1/2 in diameter. One button has smaller holes than the other two and maybe a bit more oil slick colour. Two of the buttons have small shallow back edge chips, really minor and not visible when affixed to a garment (see photo). Otherwise, these are very nice and would look great on the right garment.
