3 Vintage Carved Mother of Pearl Sewing Buttons with Shank

Description

Up for consideration are three vintage (older?) carved mother of pearl used clothing buttons with metal shanks.  I do not know if these are what are called Bethlehem Pearl Buttons.  The measure about 13/16".  The buttons are in used condition with surface wear from use or storage and there are some discolored areas or they just need a cleaning.  Some of the carved tips may be missing - I do not know what these looked like new.  Please review the photos for more details and contact me if you have any questions.  Happy sewing, collecting or crafting:)!
I will be selling a variety of family clothing buttons accumulated by 3 generations or more of sewers in my family (at least one generation prior to my mother, my mother and my sister).  Some buttons are from discarded clothing and others are new with some carded.  I am listing them under the vintage category since I am not sure of the age.
PLEASE NOTE:
I am NOT an expert on buttons and I am not familiar with all the terminology and intricacies of button collecting.  I have a hard time identifying the material and may have some plastic with glass or other mix ups. These buttons were thriftily saved by generations of sewers and used for that purpose.  So please refer to the images for details and contact me if you have any questions and I will do my best to answer them.  I will also be listing other sewing items such as thread, zippers, notions, etc. over the next few months.   Thank you for looking!
I will be happy to
