Anyone ID These Military Buttons...WWI?

[cowtownkid]

Hello Folks,

I found these buttons years ago (1998) at an 1890's house that had gone through a complete restoration. I buddy of mine bought the house and I found and kept these four...I gave him four similar buttons. I believe they are WWI era due to the look of the airplane prop on one of the buttons but not sure. Any help would be appreciated and also if of any value.

Thanks for looking!
