Collectible coins encompass a wide range of types, including patterns, trial coins, and commemorative issues. Patterns are experimental coins that are designed to test new designs or compositions and are often struck in small quantities, making them highly sought after by collectors. Trial coins, specifically from the year 1813, typically served as test pieces for proposed monetary changes but were not intended for general circulation. These coins often reflect unique design elements that differentiate them from regular issue coins of the same era and can command significant interest in the numismatic community.
