Produced from 1849 to 1889, these Gold Dollar Coins are the smallest denomination of Gold currency produced by the U.S. Mint. Throughout its minting, the Gold Dollar coin was produced in three types, with small differences between the three. The obverse of all three features a crowned image of Lady Liberty surrounded by 13 small stars, representing the original 13 colonies. The reverse shows a wreath encircling the coin's denomination and date. Type 1 coins, minted from 1849 to 1853, are 13 mm across while Type 2, minted from 1854 to 1855, were thinner and slightly larger at 15 mm across, and Type 3 coins, also 15 mm across, minted from 1856 to 1889 are the most common Gold dollar.
