Presidential Dollars are a series of coinage issued by the United States Mint, featuring portraits of U.S. Presidents on the obverse and a distinctive edge inscription. The 2012 edition includes coins honoring Presidents Chester A. Arthur, Grover Cleveland, Benjamin Harrison, and William Howard Taft. Each coin is composed of a golden hue, primarily made from a manganese-brass alloy, and was produced as part of a collectible initiative starting in 2007. The 1 One Dollar denomination signifies its face value, while its numismatic appeal lies in both the historical significance and the series' limited production runs.
