Collectible coins are often categorized based on their historical significance, rarity, and condition. In the United States, various types include patterns, which are experimental designs created for potential future coins. Trial coins, such as those from 1805, are often struck to test new designs or production techniques. These coins can hold substantial value for collectors due to their limited availability and unique historical context. Patterns and trial coins are particularly sought after in the numismatic community for their role in the evolution of U.S. coinage.
