Composition and Specifications

New standards were established for the eagle denomination under the Coinage Acts of 1834 and 1837. The Liberty Gold Eagle carried a composition of 90% gold and 10% copper with a weight of 16.718 grams. This compared to the previous standard of 91.67% gold and 8.33% silver and copper with a weight of 17.50 grams. The remaining specifications for the Liberty Eagle included a diameter of 27 mm and a reeded edge. Each coin will have a net weight of .48375 troy ounces of pure gold.

During the course of the series, coins were struck at the Philadelphia, New Orleans, San Francisco, Carson City, and Denver Mint facilities. The coins struck at Philadelphia Mint do not contain a mint mark. The coins struck at the remaining facilities have the mint mark located on the reverse of the coin below the eagle.

Quality of striking varies with each issue, as does the overall appearance. Carson City and New Orleans issues, especially the earliest are usually the most poorly produced issues, although exceptions exist. Many pieces show extensive bagmarks, although a few nearly pristine pieces are also known to exist.
