The Thomas Jefferson Coin and Currency Set. In 1994, the US Mint introduced its first ever coin and currency set by recognizing and honoring Thomas Jefferson's contributions to America's coinage and currency system. The Thomas Jefferson Coin and Currency Set included the Thomas Jefferson Commemorative Silver Dollar, a Thomas Jefferson five cent coin and a Thomas Jefferson two dollar Federal Reserve Note for the currency. In addition, the Mint included a six page booklet titled "Thomas Jefferson: Father of America's Decimal Coinage System." The coin and currency set booklet provided the background and history of Thomas Jefferson's vision of a simple monetary system and told of the challenges he faced and overcame to secure our decimal system.
