August 2, 2009 The 1880 Gold Eagle was produced at 4 US Mints; Philadelphia which is shown as 1880-P in this ; Carson City which is shown as 1880-CC in this ; New Orleans which is shown as 1880-O; San Francisco which is shown as 1880-S in this . To determine which coin you have it is necessary to locate the mint mark. This mark will be found on the reverse side of the coin just beneath the eagle. A letter "O" is for New Orleans. A letter "S" is for San Francisco. The letters "CC" are for Carson City. If there is no letter beneath the eagle then the coin was minted at Philadelphia. The circulated and uncirculated values for these coins are shown in the following list.
