Collectible coins are often categorized into various types based on their historical significance, metal composition, and rarity. The United States has issued a variety of one-dollar coins, including gold dollars. The 1861 Gold Dollar, minted in Dahlonega, is particularly notable due to its limited mintage and the historical context of the Civil War era. Coins from the Dahlonega Mint are especially sought after by collectors due to their regional significance and scarcity.
