Modern Commemorative Coins are a subset of collectible coins issued by the United States Mint, celebrating significant events, people, or places. The 1987 commemorative set includes the Constitution Bicentennial Coin, honoring the 200th anniversary of the U.S. Constitution. These coins were produced in limited quantities and often appeal to collectors due to their historical significance and numismatic value. Collectors often seek complete sets, which may include silver dollar coins and half dollars from that year.
