1879-CC $20 (1879-CC Double Eagle) PCGS AU53. Type 3 Double Eagle. This lustrous branch mint 1879-CC Double Eagle shows attractive, underlying color. Bright mint luster is seen in protected areas. The coin is boldly struck with full details on the obverse stars, Libertys hair, and the design elements of the reverse. The grade is confirmed by the separation of the lines of Libertys hair and the back portion of the coronet. For the grade, the surfaces are clean and free of major distractions. The vertical scratch marks on the obverse are on the holder not the coin.

The first Carson City coin was the Liberty Seated 1870-CC dollar. A person who had deposited silver at the mint received 2303 silver dollars. Shortly afterwards, gold eagles, half eagles and double eagles were struck. The Carson City Mint did not strike coins made of copper or nickel, and it never struck half dimes, gold dollars, quarter eagles, or three dollar gold coins.

In 1873 silver was demonetized; however, the Bland-Allison act of 1878 required the Treasury Department to coin two to four million sliver dollars each month. The act attempted to keep silver at artificially high levels. Large quantities of Morgan Dollars were minted, but they did not circulate well and were kept in Treasury storage vaults.

In 1884 Democrat Grover Cleveland became president. He fired all the Republican appointees including the top officials at the Carson City Mint and shut it down. A year later it reopened as an assay office. When Republican Benjamin Harrison became president, he fired Clevelands appointees and replaced them with Republicans. In 1889 coining operations at Carson City resumed.

In 1890 the Sherman Silver Purchase Act modified the Bland-Allison Act. Under it the government was required to purchase 4.5 million ounces of silver per month which was to be paid with bonds that could be redeemed for gold or silver. Much to the surprise of the officials, most bond holders chose gold, which depleted the governments gold reserve. This instability caused the panic of 1893, which led to the repeal of the Sherman Act and slowed the production of silver dollars. At the same time the Nevada mines were no longer as plentiful as they had been before. Combined with a low silver price, a scandal (a worker tried to smuggle gold out of the mint in his lunch box), and a struggling economy, the Mint Director, Robert Preston, ordered the Carson City Mint as a coining facility closed in 1893.

Longacres double eagle design was a new concept that endured well past the turn of the century. When Longacre first came to work at the Mint, he was opposed by Franklin Peale, the Chief Coiner. Peale was probably responsible for some blundered dies that Longacre was criticized for making. Peal was involved in a private, illegal medal manufacturing business using Mint facilities. He was concerned that this new political appointee would interfere with his business, and he resisted Longacres appointment as Chief Engraver. In the end Peale was found out and fired in 1854. Longacre flourished in his position and was responsible for creating many new designs including the Indian Head cent, the Two-cent piece, the Shield nickel, the Liberty Head gold dollar, the Indian Princess gold dollars, the Three dollar gold piece, and, the Liberty Head double eagle.
