In 1907, the United States Mint produced trial coins, commonly referred to as patterns, to test new designs and compositions before official production. Among these, the 20 Dollars gold coin, also known as the Double Eagle, featured innovative designs, including those by renowned sculptor Augustus Saint-Gaudens. These patterns are highly sought after by collectors due to their limited mintage and distinct variations, making them valuable additions to numismatic collections. The 1907 Double Eagle patterns showcase the transition in coinage design and remain iconic in American coin history.
