The Presidential Dollar Series, launched in 2007, honored each U.S. president with a unique coin design. The series continued until 2016, with each president being featured on a separate coin issued in chronological order of their presidency. These coins are often collected by numismatists and history enthusiasts. If your set includes all four coins in Uncirculated condition and is presented in a case, it may hold value to collectors, especially if it is well-preserved and accompanied by any original packaging or documentation.
