Collectible coins can be categorized into various types, including historical coins, commemorative coins, error coins, and bullion coins. The United States has a rich history of collectible coins, including the 2.50-dollar gold coins, also known as "Quarter Eagles," which were minted from 1796 to 1929. The 1860 issue was produced in Philadelphia and holds significance for collectors due to its historical context and gold content. Colorado gold coins, often sought after by numismatists, may refer to coins minted from gold sourced in Colorado during the 19th-century gold rush.
