Colonial Currency of the 1700’s, Confederate and Fractional Currency of the 1860’s, United States Notes, Silver Certificates, Gold Certificates, National Currency and Federal Reserve Notes are among the currency LCGON inventories. Historically relevant, each series in part tells the story of U.S. history and economy. Artistically rendered, and symbolically rich, they are esthetically pleasing to collect. Historically, U.S. currency has increased in collectible value (beyond the face value) steadily over the years.
