Collectible coins are numismatic items that can be valued for their historical significance, rarity, and condition. The United States quarter, specifically the 25-cent coin, has seen various designs and issues since its inception. Privately issued patterns, such as those from 1860, are experimental coins created by private mints or individuals, often lacking official governmental endorsement. These patterns can offer insight into the coin design process and sometimes feature unique or unadopted designs, making them sought after by collectors.
