Antique small BS BLUE & white pinback pin button

Antique small BS BLUE & white pinback pin button We can not find any information on this. This includes the buttons in the photos. They show well and have normal wear from age and use. This is older, but not marked, so I am unsure of the age. The coin in the photos is in the photos to show size and not included. Roughly the size of dime. I have many similar buttons listed.
