The magnificent 1907-1933 $20 gold piece (or double eagle) was designed by Augustus Saint-Gaudens and depicts Liberty striding forward with sun rays in the background. The reverse features similar sun rays and an eagle in flight. The 1910-D double eagle was struck at the Denver Mint (the "D" mint mark is found above the date on the obverse). This stunning $20 coin offers size, weight, superb artistry and precious 90% fine-gold composition.
