The story
Theodore Roosevelt called American coinage 'atrocious hideousness' and hired the greatest sculptor of the age to fix it. Saint-Gaudens' eagle — and the standing Liberty in a feathered bonnet — was the result, struck from 1907 until gold coinage died in 1933. The eagle was the denomination the dollar was defined against: $20.67 per ounce, until 1933 revalued the world.
Early 1907 eagles omitted 'In God We Trust' — Roosevelt considered the motto on money blasphemous. Congress overruled him within a year.
