Collectible coins encompass various categories, including patterns, which are experimental or trial pieces created to test designs before production. In the United States, the 1873 P25c refers to the 25-cent coin, specifically the quarter, produced during a time when the U.S. Mint was experimenting with different coin designs. Patterns from this era are highly sought after by collectors due to their rarity and historical significance, often representing pivotal moments in U.S. minting. The 1873 patterns are particularly notable as they reflect changes in coinage design and denomination during the transition to newer minting standards.
