Presidential Dollars are a series of coins issued by the United States Mint, featuring the portraits of U.S. presidents in the order they served. The 2016 series included coins honoring presidents such as Ronald Reagan, John F. Kennedy, and Harry S. Truman. Each coin is issued in a standard one-dollar denomination and showcases an engraving of the president's name and term dates on the edge. Their collectible value is influenced by factors such as minting errors, condition, and overall demand.
