Collectible coins, particularly those from the United States, often include various types such as patterns and trial coins. Patterns are experimental coins struck to test designs or compositions before full production, while trial coins serve similar purposes in evaluating minting processes. The 1880 Philadelphia pattern coins, specifically five-dollar pieces, are notable examples, with limited mintage and unique designs, making them highly sought after by collectors. These coins can provide insight into the historical context and artistic direction of U.S. coinage during that period.
