Collectible coins are categorized into various types based on their unique characteristics, historical significance, and production variations. In the United States, notable examples include trial coins, which are experimental pieces made to test designs and minting techniques before official production. The 1794 silver dollar, minted in Philadelphia, is particularly renowned among collectors for its historical context as one of the first silver dollars issued by the United States, and it reflects the early efforts to establish a national currency. Additionally, patterns are specialized coins that showcase proposed designs that were not adopted for regular circulation, making them highly sought after by numismatists.
