Double eagles are another type of collectible coin rooted in a key period of American history - which makes collecting them interesting for both coin and history aficionados.
Would there have been a double eagle coin without the California Gold Rush? Very likely not. The double eagle, a $20 U.S. coin, was first minted in 1849, two coins in proof, after an Act of Congress authorized them. Prior to this there was neither gold in quantity to mint them or a practical necessity for a $20 coin. Double eagles began to be minted regularly the following year, in 1850, and continued to be until 1933. Before 1850, the largest coin denomination was the $10 eagle. Since the face value of the new coin was twice that of the eagle, it was called the double eagle.
