The Liberty Gold Dollars were struck on planchets of 90% gold and 10% copper. With a diameter of just 13 mm, these coins represent the smallest regular coins ever produced by the United States Mint. The coins have a weight of 1.672 grams (25.8 grains) and a reeded edge.
Coins of the series were struck at the Philadelphia, Charlotte, Dahlonega, New Orleans and San Francisco Mints, representing all mints in operation during the short history of the series. Those struck in Philadelphia do not have a mintmark, while the coins struck at the other mints have the mint mark located on the reverse, directly under the wreath.
