I know what it is!

Great Seal button. US military.

1902 to present.

I agree !

It does not appear to have a rim, which means it dates to 1902-1910.

To be sure, can you show us the back? If its button like, then the above description is right on. But it also resembles a collar disk, in which case it was for a detached enlisted soldier (and it would date a bit later).
