What are the four gold coins which the eagle appears on?

I remember the first time I held an American Gold Eagle—it had this powerful eagle design that felt truly symbolic. The same majestic bird appears on the Indian Head Gold Eagle, the Saint-Gaudens Double Eagle, and the $10 Liberty Gold Eagle. It’s fascinating how BOLD designs featuring eagles have stood the test of time, representing strength and freedom across different eras of U.S. coinage.
