Collectible coins encompass various categories, including patterns and trial coins. The 25-cent quarter, a significant denomination in the United States, has seen numerous designs throughout its history. In 1871, trial coins were produced in Philadelphia as part of the Mint's efforts to evaluate designs before mass production. These trial coins, often referred to as patterns, are sought after by collectors due to their rarity and historical significance.
