The double eagle was a new gold denomination created by the Coinage Act of 1849. The coins would carry a value of $20, the highest for a U.S. coin at the time and double the value of the eagle, which was created by the Coinage Act of 1792. The higher denomination was desired to strike the massive amounts of gold discovered in California into coin.
The Liberty Gold Double Eagle was designed by James B. Longacre. The new design was first struck in 1849 (a unique pattern coin) and produced for circulation starting in 1850. The obverse features the head of Liberty facing left with thirteen stars surrounding. The reverse features a modified version of the heraldic eagle with two scrolls. A circle of thirteen stars appears above with inscriptions around the entire design.
The coins were struck in 90% gold and 10% copper. Each coin contains .96750 ounces of pure gold. During the course of the series, which last more than half a century, coins were struck at Philadelphia, Carson City, Denver, New Orleans, and San Francisco.

The Standing Liberty Quarter was issued from 1916 to 1930. Many consider this coin to feature one of the most beautiful United States coin designs from the Renaissance era of US coinage. The design, featuring a standing image of Liberty holding a shield and olive branch, was created by Hermon A. MacNeil, a sculptor from Massachusetts. The reverse design features an eagle in flight. During the course of the Standing Liberty Quarter series, coins were minted at the Philadelphia, Denver, and San Francisco Mints. The lowest mintage occurred with the 1916 coin, when only 52,000 were minted.

The nickel denomination saw its second design with the Liberty Nickel, introduced in 1883. The coin had the same composition as the Shield Nickel fore it, with 75% copper and 25% nickel. The Liberty Nickel was minted only at the Philadelphia Mint until the last year of production when coins were also minted in Denver and San Francisco. These were the first coins of the denomination minted somewhere other than Philadelphia. The Liberty Nickel was well circulated, and has a few notable key date coins that are rare across all grades. Proof coins were minted in every year of issue.
