Collectible coins, particularly in the context of the United States, encompass a wide range of issues, including commemoratives, bullion, and rare patterns. The P25c refers to a specific type of quarter, and patterns are experimental coins struck by the U.S. Mint to test new designs or compositions before mass production. The 1891 patterns are particularly notable, as they were created during a period of artistic experimentation in U.S. coinage, showcasing distinct designs that were never officially adopted for circulation. These coins are highly sought after by collectors due to their rarity and historical significance.
