Need help with ID of this Eagle button.

[seatedhalf]

I can't seem to find this one on the manufacturers site. None of the eagles I saw matched this one. Can anybody help me? I know very little about buttons.

I assume its an Infantry coat button. What is approximate era?

Tice has this button listed as G1215A83 U.S Federal (Yankee) Infantry
