Collectible coins, particularly within the United States, include a diverse range of types such as patterns, trial coins, and specific denominations like the 1 Cent Penny. One notable example is the 1856 Flying Eagle cent, which is considered a pattern coin produced in Philadelphia. These coins were minted to test designs and metal compositions before official production, making them highly sought after by collectors. As rare items, trial coins often reflect historical significance and are valued for their uniqueness and connection to numismatic history.
