What is the 1870-CC Double Eagle?
The 1870-CC Double Eagle is a $20 gold coin minted at the Carson City Mint in Nevada. The “CC” mintmark signifies that it was produced at this historic facility, which operated during the 19th century to refine gold and silver from the rich mines of the West.
History of the 1870-CC Double Eagle
1. The Carson City Mint’s Beginnings
The Carson City Mint was established in 1863 to help process the enormous gold and silver deposits found in the Comstock Lode. However, due to delays in construction and funding, it wasn’t until 1870 that it finally began producing coins.
