Collectible coins are coins that are sought after by numismatists and collectors for their historical significance, rarity, and condition. In the United States, notable collectible coins include various types such as patterns, which are trial or experimental coins created to test new designs and compositions. One example is the 1863 trial coins produced in Philadelphia, which are notable for their unique characteristics and limited availability. These coins often have specific aesthetic and production features that make them highly valuable to collectors.
