Collectible coins encompass a variety of types, including patterns, which are experimental designs created by mint officials to evaluate potential new coins. In the context of the United States of America, patterns may include various denominations, such as the 10-cent pieces designated as P H10c. These coins are often produced in limited quantities, making them highly sought after by collectors. Their rarity and historical significance contribute to their value in the numismatic market.
