The mint mark on the US 1849 One Dollar coin is located on the reverse [tails] side of the coin under the wreath. There will be a "C" for Charlotte, North Carolina mint ; a "D" for Dahlonega, Georgia ; an "O" for New Orleans, Louisiana.

For coins dated 1906 to the present, it means the coin was made at the Denver Mint. A "D" mint mark on an old (1838-1861) gold coin means it was made at the long-closed gold coin mint at Dahlonega, GA.

In average condition, about $500 for its gold content. If the coin has only slight wear AND there is an "O" mint mark on the back, it has a higher collector's value, though - $700+ depending on the amount of wear.
If worn, in numismatic Good to Fine condition, about $400 regardless of mint mark. If the condition is better than that, a Philadelphia issue (no mint mark) would retail for $420 to $450, and a New Orleans ("O") coin would go for $750 to $2800
