All coins struck at Charlotte are either scarce or rare today. Heading the list is the 1849-C gold dollar with open wreath on the reverse, of which fewer than a half dozen specimens are known.

Dahlonega Mint (1838-1861): The history of the Dahlonega Mint is similar to that of Charlotte. Gold produced in the Dahlonega area of Georgia was converted into $1, $2.50, $3, and $5 pieces from the period 1838 through 1861. The mint closed at the advent of the Civil War. Dahlonega coins have the mintmark D, not to be confused with the same mintmark later used for Denver coins, for the Dahlonega Mint operated 1838-1861, decades before the Denver Mint did. All Dahlonega gold coins are either scarce or rare and as a class are more elusive than their Charlotte Mint counterparts.

San Francisco Mint (1854 to date): During the gold rush era in California many banks and private individuals produced coins. In 1854 the federal government opened a mint there using a building and equipment purchased from a private firm. Known as the San Francisco Mint, the facility used the S mintmark on its pieces. Coins were produced at San Francisco from 1854 until 1955, and again from the late 1960s until the present time. Over a period of years the San Francisco Mint has produced pieces in all metals. From 1968 onward, Proof sets for collectors have been produced there.

Among rarities struck at the San Francisco Mint are such issues as the 1870-S half dime, 1894-S dime, 1870-S silver dollar, 1854-S $2.50, 1870-S $3, and 1854-S $5.

Carson City Mint (1870-1893): In 1870 a mint was opened in Carson City, Nevada to take advantage of silver (and to a lesser extent gold) found in the Comstock Lode in Nevada. Bearing CC mintmarks (the only mintmark with more than one letter), Carson City coins were produced from 1870 through 1885 and again from 1889 until 1893. Today the mint building serves as the Nevada State Museum. Carson City coins were produced in silver and gold.

Among the rarities produced at this mint are the 1873-CC dime without arrows (which is unique), the 1873-CC quarter without arrows (only three or four are known), the 1876-CC twenty-cent piece, and the 1870-CC $20.
