1884-CC $20 (1884-CC Double Eagle) NGC AU55. Type 3 Double Eagle. This Carson City, Type 3 1884-CC Double Eagle has traces of mint luster in protected areas of both sides. The coin is well struck with full details on the obverse stars, Libertys hair, and all of the design elements of the reverse. For the grade, the surfaces are original, clean and free of individual marks worthy of description. The apparent reverse scratch through the left reverse is on the holder not the coin.

When first discovered, gold and silver found in Nevada had to be shipped over the Sierra Nevada Mountains to the branch mint in San Francisco. This trip was dangerous and expensive. The Nevada mine owners asked Congress to establish a branch of the mint in their state, and legislation was enacted in 1863. Carson City was chosen as the location for the mint facility because it was near some of the major mining sites.

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.

The design change that brought about the Type 3 double eagle was the denomination. It went from TWENTY D. to TWENTY DOLLARS. Like the addition of the motto to the reverse of the previous double eagle, it did not cause any major change in the rest of the coins design. William Barber who by then was the Engraver following Longacres death in 1869 made the modification. Later, his son Charles further modified the reverse of the double eagle by smoothing the back of the eagles neck.
