Collectible coins are items of interest to numismatists, which include various types such as patterns and trial coins. Patterns are experimental coins created to test designs and production methods, often not intended for circulation. The 1794 One Dollar coin, struck in Philadelphia, is particularly significant as it is considered one of the first silver dollars issued by the United States and holds immense value among collectors. Trial coins, similar to patterns, are struck to evaluate design feasibility and may differ from the final issued currency.
