The $20 Liberty Gold coin, minted in the United States from 1849 to 1907, features a design by George T. Morgan. The 1906 Denver coin is part of this series and showcases the classic Liberty head on the obverse and a majestic eagle on the reverse. These coins are composed of 90% gold and 10% copper, making them both a historical artifact and a valuable collectible in numismatic circles. The 1906 Denver issue is particularly sought after for its lower mintage compared to other years.
