In the realm of collectible coins, the Two and a Half Dollar denomination, often referred to as "quarter eagles," represents a significant category. These coins were primarily minted in the United States from various gold sources, with notable issues originating from territorial mints in the 19th century. The year 1861 is particularly important due to the Civil War context, leading to the production of both federal and territorial coins, with the latter being struck in regions seeking independence or altered economic conditions. Collectors highly value these coins for their historical significance and rarity, especially those with unique minting characteristics or regional designs.
