Of course, I had to pick up the sister to the 1-A

1882-CC $20 MS60 NGC. Variety 1-B. In 1882, coining and refining operations at the Carson City Mint increased over previous years. Double eagles, not struck at the Nevada branch mint since 1879, were struck to the extent of 39,140 pieces. The Carson City Mint was of advantage to miners and mine owners as a convenient place to deposit their gold in exchange for coins or bars. Double eagles that did not circulate locally were eventually exported, and many of the pieces known today were repatriated from foreign trade caches. Uncirculated coins are scarce and in high demand. 

This piece is sharply struck from dies that do not show the lapping seen on many Carson City double eagles at the eagle's tailfeathers and Liberty's neck truncation. Satiny peach-gold surfaces exhibit olive patina amid the scattered abrasions. The vast majority of Uncirculated 1882-CC twenties are heavily abraded, thus the markers of quality more often than not are a sharp strike and unworn devices, as this piece possesses.
