1872-CC $20 (1872-CC Double Eagle) NGC AU55. This boldly struck, Carson City 1872-CC Double Eagle shows full details on the obverse stars and all of the design elements of the reverse. The coin is a medium orange-gold color with light rose highlights in protected areas. Sufficient separation exists in the lines of the hair and the back portion of the coronet to support the grade. A fair amount of bag marks are present, but these are typical for the issue. There is remaining, muted mint luster in protected areas.

Longacres design for the double eagle shows a Liberty head facing left wearing coronet inscribed LIBERTY. Her hair is tightly tied in the back with two loose curls hanging down her neck to the end of the truncation. She is surrounded by thirteen six pointed stars with the date below. Dentils are near the edge on both sides of the coin. The reverse shows a heraldic eagle with elaborate ribbons on both sides of the shield extending from the top corner down to the eagles tail feathers. The ribbons are inscribed, on the left E PLURIBUS and UNUM on the right. The ribbons were added to the design to symbolize the denomination since this was the first twenty dollar coin. There is an oval of thirteen stars above the eagles head and an arc of rays from wing tip to wing tip behind the upper half of the oval. UNITED STATES OF AMERICA is in an arc above the eagle, and the denomination TWENTY D. is below. The CC mint mark is between the tail feathers and the N of TWENTY.

The motto IN GOD WE TRUST was added to the original double eagle by enlarging the oval of stars above the eagles head and placing the motto in it. This modification did not require a major alteration of the design as was the case with adding the motto to the lower denominations. It was made at the behest of Salmon P. Chase, Secretary of Treasury and Congress because of pressure brought about by the Reverend M.R. Watkinson of Ridleyville, Pennsylvania.

Authorized in 1863, the Carson City Mint began coinage in 1870 and continued until 1893. It was then operated as a government assay office until 1933 when it was closed as a cost cutting measure. During its operation the Carson City Mint made fifty-seven different types of gold coins. It also converted gold bullion and oar into gold bars which were shipped to San Francisco for coinage there. Coins issued from Carson City used the CC mint mark. Originally established to convert silver from the Comstock Lode to coinage, the Carson City Mint also processed gold in to gold coins.

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.

Between 1870 and 1873, mintage at Carson City was limited because of political reasons. The Mint Superintendent, H.F. Rice was dismissed because of claims that the mint issued some light weight and debased coins. Rice could have been executed. This partly verified information led to frequently seen edge test marks on the gold pieces of this period. Those who wanted the Carson City Mint closed use this discovery to urge the closing. Their real motive was that they wanted the lucrative shipping contracts to move the oar to San Francisco.
