Collectible coins refer to various types of currency that are sought after by collectors for their historical significance, rarity, or unique features. Within the context of the United States, specific patterns like the 1871 P3C coin exemplify unique designs or characteristics that were often trial pieces or prototypes. These coins play an important role in numismatic history, reflecting the evolving design and minting practices of the era. Patterns can be especially valuable due to their limited production and the insights they provide into the coinage process.
