Collectible coins are a category of numismatic items that are valued for their rarity, historical significance, and condition rather than just their face value. The Two and a Half Dollar coin, often referred to as the "quarter eagle," was minted in the United States as a gold coin, notably during the 19th century. The American Liberty Gold coin from 1851 is a prime example, reflecting both artistic design and the economic context of its era. Such coins are sought after by collectors for their intrinsic gold content and their appeal as historical artifacts.
