Collectible coins, also known as numismatic coins, include items that are valued for their historical significance, rarity, and condition rather than just their face value. In the United States, notable examples include the Twenty Dollar gold coin, often referred to as the Double Eagle, which was first issued in 1849. The Braided Hair Cents were minted from 1839 to 1857, featuring a unique design that highlights Liberty with braided hair. The year 1850 saw various important transitions in coinage, reflecting changes in both design and economic contexts during that time. Collectors often seek coins like these for their artistic value and historical context.
