Where have our Eagles gone?

[M. Demetrius]

Jeff, I think you're right. And the styles probably did change over time. We all want to think they looked like the eagles atop American flags, but they evidently didn't. Some are shown with upraised wings, others outstretched, etc. And the coin representations of the American Eagle have changed considerably over the 300 years or so of American coinage. Why should the Romans have kept the same design over three times that long of a span?
