Collectible coins are items sought after by numismatists and collectors, typically due to their historical significance, rarity, or unique features. In the United States, the 10 Cents Dime is a denomination that has been produced in various forms since its inception. Among these, trial coins and patterns from the 1860s serve as prototypes and experimental issues, often not released for general circulation. These trial coins are valuable to collectors as they represent critical developments in coin design and minting processes.
