Modern Commemorative coins in the United States, introduced in 1982, are designed to honor significant people, events, and themes in American history. The 1988 One Dollar coin commemorates the bicentennial of the United States Congress. These coins often feature unique designs and, unlike regular currency, are produced in limited quantities, making them appealing to collectors. The 1988 commemorative issues typically have a higher intrinsic value due to their historical significance and collector demand.
