Hi!  I'm hoping someone can give me an age estimate on these irridescent striated celluloid buttons.  They measure 2-1/8" in diameter.  Thanks so much in advance 🙂

Your buttons are celluloid "tight tops" they are from the early 1900's. If they are very large they were probably worn on long cloth "duster" coats carried in the trunk of open top roundabout autos to keep the dust off. -Carol- BB Moderator

Thank you for posting this, I forgot what this type of button was called.
