Collectible coins, particularly within the United States, encompass various types including the Five Cents Nickel and the Half Dime. Patterns and trial coins, such as those minted in 1863, serve as experimental issues that test new designs or compositions before official production. These pieces often have limited mintage and unique characteristics, making them highly sought after by collectors. Their historical significance and rarity can greatly influence their value in the numismatic market.
