Collectible coins are numismatic items valued for their historical significance, rarity, and condition. In the United States, coins such as the 1877 Pattern coins are notable for their unique designs and limited mintage, often sought after by collectors. Patterns are experimental pieces struck to test new designs or compositions, making them particularly desirable in the numismatic community. The 1877 date features coins that showcase the artistic transition in U.S. coinage during that period, reflecting the cultural and economic factors of the era.
