Collectible coins often include various types, such as numismatic coins, bullion coins, and special edition releases. The United States has a rich history of collectible coins, including the One Dollar coin series. Gold Dollars, minted in the 19th century, are particularly notable, with the 1850 Gold Dollar minted at the Dahlonega Mint being a prime example. These coins are valued for their historical significance, rarity, and gold content.
