Mystery V S button what is it?

[Flashlarue]

Button is made by M. C. Lilley & Co. Columbus O. It is a 3 piece high dome brass button. I can only guess 5 possible V names; Virginia, Vermont, Volunteer, Veteran, or Veternarian. Can anyone identify this button?

That is a button for the Sons of Veterans of the United States of America.  In 1925 that organization changed its name to Sons of Union Veterans of the Civil War.
