Collectible coins are often categorized into various types, including patterns and trial coins, which are experimental pieces created to test designs or minting techniques. The United States has issued numerous collectible coins, one of which is the five-dollar denomination, featuring various designs that reflect historical events, notable figures, or national symbols. In 1987, specific minting projects may have included trial coins or patterns that were produced in limited quantities and are sought after by collectors for their rarity and significance. These coins often hold value beyond their face value due to their historical context and numismatic importance.
