Small Button or Snap?

[Indians84]

Here is a small button? I found recently. It came from a homestead circa 1868. It looks like it could be a snap. The back reads "Mills Military Fastners" There is also a symbol which looks like an arrowhead.
Thanks for any help.

Yes I agree. US Great Seal. Commonly referred to as Eagle Snaps.
