It means the coin was minted in New Orleans. "CC" appears on coins minted in Carson City so it's not something special or distinctive about a Morgan dollar; several other denominations were minted there as well.
The mintmark position on all Morgan dollars is on the reverse (back) of the coin, below the eagle's tail feathers. Other potential mintmarks would be "S" (for San Franscisco) and, in 1921 only, "D" (for Denver). A lack of mintmark signifies that the coin was minted in Philadelphia. Philadelphia didn't use the P mintmark on $1 coins until 1979.
The 'O' mint mark on US Coins signifies the New Orleans Mint, which closed at the beginning of the Civil War in 1861, but re-opened in 1879. It closed permanently in 1909.
An "O" mint mark on any US coin minted from 1838 to 1861 and 1870 to 1909 indicates that it was made at the New Orleans Mint.

If you mean a dollar coin made in 1935 or before that are the only real silver dollars, mintmarks (letters) are used to show the Mint a coin was struck at. A coin with no mintmark was struck at the main Philadelphia Mint, the branch Mints are San Francisco "S"/ New Orleans "O"/ Carson City "CC" and for the 1921 Morgan only "D" for Denver.
