The American Gold Eagles are made in four denominations that contain 1 oz, 1/2 oz, 1/4 oz and 1/10 oz of gold. The obverse features a modified rendition of the Augustus Saint-Gaudens design used on the U.S. twenty-dollar gold pieces from 1907 until 1933. This series has run from 1986 to the present date in both an Uncirculated and Proof finish, providing diversity for both the collector and investors alike.
