Collectible coins, particularly from the United States, encompass a diverse range of items including patterns, which are experimental or prototype coins struck for evaluation before final design approval. The 1873 patterns, particularly notable for their unique designs and historical significance, were created during a period of transition in U.S. coinage. These coins often serve as key examples for collectors due to their limited mintage and the insights they provide into the numismatic evolution of that era. The PH10c designation refers to a specific pattern coin type, highlighting its categorization in the broader context of collectible U.S. coins.
