Collectible coins represent diverse categories, including historical, commemorative, and rare coins. Specific to the United States, collectible coins may originate from notable minting events, regions, or eras. The John Parsons Company, known for its mining-related ventures, has ties to specific coins minted around significant historical events, such as the Civil War in 1861. Examples include coins linked to the Tarryall Mines in Colorado, which reflects the mining boom and economic activity of the region during that period.
