Collectible coins, particularly in the context of the United States, include various denominations and types that have historical and numismatic significance. The $1 Gold Dollar, minted in the mid-19th century, is notable, especially coins struck in Dahlonega, Georgia, from 1838 to 1861. The 1856 Gold Dollar from Dahlonega is particularly sought after by collectors due to its limited mintage and the unique historical context of the Dahlonega Mint. These coins often carry premiums based on their rarity, condition, and demand among numismatists.
