Based on the provided information, United States dollar coins can be procured from both official government sources and private numismatic companies. The primary governmental source is the United States Mint itself. As the official producer of the nation's coinage, the U.S. Mint operates a shop on its website where consumers can directly purchase various one-dollar coins, often including newly released and collectible editions.
In addition to the Mint, a robust market exists among private dealers who specialize in coins for collectors. For example, Littleton Coin Company is a retailer that offers a vast selection of U.S. one-dollar coins. These private entities typically carry a wide historical range of currency, from the earliest American dollar coins like the Flowing Hair and Draped Bust dollars of the 1790s to later popular series such as the dollar. These companies cater specifically to the numismatic community, providing access to coins that are no longer in general circulation.
