This is a lot of Victorian or vintage buttons or shirt studs. There are a total of 22 buttons. Some are mother of pearl and some are abalone. None of the buttons are marked that I can find. Five of the abalone buttons are set in gold tone. All of the buttons have clips on the back. They all have shanks too. The buttons are all in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
