The Nova Constellatio

The 1783 Nova Constellatio pattern coins represent a brilliant solution to the foremost economic problem facing the American States during the Revolutionary period – how to create a national currency that incorporated the hodge-podge of monetary systems in use at the time.

The Nova Constellatio coins are the first coins struck under the authority of the United States of America. These pattern coins were struck in early 1783, and are known in three silver denominations (1,000-Units, 500-Units, 100-Units), and one copper denomination (5-Units). All known examples bear the legend “NOVA CONSTELLATIO” with the exception of a unique silver 500-Unit piece.

Robert Morris, the Founding Father credited with financing the Revolutionary War, spent two years working on the Nova Constellatio patterns. Morris was unanimously elected the Nation’s first Superintendent of Finance in 1781; on February 21st of the following year, Congress passed the following resolution:

That Congress approve of the establishment of a mint; and, that the Superintendent of finance be, and hereby is directed to prepare and report to Congress a plan for establishing and conducting the same.

The financier’s plan, developed with his assistant, Gouverneur Morris, was ambitious: he hoped to unite the Nation with a monetary unit that would allow for easy conversion from British, Spanish, Portuguese, or State currencies to U.S. funds. More importantly, Morris’s proposal would be the first system of coinage in Western Europe or the Americas to use decimal accounting – an innovation that has been adopted by every nation on earth in last two centuries.

Due to the new government’s precarious financial situation, Congress did not put Morris’s plan into effect; however, Alexander Hamilton and Thomas Jefferson, became champions of the decimal concept after examining Morris’s coins. While Thomas Jefferson was in possession of the Nova Constellatio coins, he wrote a report entitled “Notes on the Establishment of a Money Unit and of Coinage for the United States”; in it, Jefferson concluded:

The Financier, therefore, in his report, well proposes that our Coins should be in decimal proportions to one another. If we adopt the Dollar for our Unit, we should strike four coins, one of gold, two of silver, and one of copper,.:

1. A golden piece, equal in value to ten dollars:
2. The Unit or Dollar itself, of silver:
3. The tenth of a Dollar, of silver also:
4. The hundredth of a Dollar, of copper.

This is the first written description of the monetary system ultimately adopted by the United States, clearly illustrating the historical importance of Morris’s patterns.

There are records of seven physical coins associated with Morris’s plan:PlainObverseQuint

1. A single silver coin of indeterminate denomination delivered to Morris on April 2nd, 1783. Upon its receipt, Morris recorded in his diary: I sent for Mr. Dudley who delivered me a Piece of Silver Coin being the first that has been struck as an American Coin.

2. A set of silver coins comprising a 1,000-Unit piece, a 500-Unit piece, and three 100-Unit pieces. These coins were struck after Alexander Hamilton visited the Treasury, initiating correspondence “On the Subject of the Coin” between Morris and Hamilton, culminating in the decision to strike a set of coins “to lay before Congress”.  These coins were later sent to Thomas Jefferson, who composed his “Notes on the Establishment of a Money Unit and of Coinage for the United States” while examining the set. Jefferson recorded the value of the set at $1.8, or 1,800-Units, indicating that its composition was one 1,000-Unit piece, one 500-Unit piece, and three 100-Unit pieces. This is the precise composition of the known silver examples bearing the legend “Nova Constellatio”.

3. A 5-Unit copper piece bearing the legend “Nova Constellatio”, which was sent to London prior to Jefferson’s receipt of the set.

After being returned to Congress, the coins were dispersed. In the mid-1840s, the 1,000-unit and 500-Unit piece from the set bearing the Legend NOVA CONSTELLATIO (A NEW CONSTELLATION) were discovered by a descendent of longtime Secretary of Congress, Charles Thomson. From this point forward, Morris’s coins would be called the Nova Constellatios.

Twenty-five years would pass before another of Morris’s coins would be found. A second silver 500-Unit piece was uncovered in 1870; however, this specimen lacked the NOVA CONSTELLATIO legend. Collectors dubbed this coin the “Type-2”, because it’s design differed from the Congressional set’s 500-Unit piece. In 2017, the designation for this piece was officially changed to “Plain Obverse” in A Guide Book of United States Coins 2017: The Official Red Book, when forensic evidence demonstrated that it was struck prior to the example from the set that was sent to Congress.

By 1900, three silver 100-Unit coins – all bearing the NOVA CONSTELLATIO inscription – would be located, leaving only the copper 5-Unit piece unaccounted for. In 1979, this coin, also bearing the NOVA CONSTELLATIO legend, was discovered in Europe. This incredible set of coins shaped how we use and handle money today.
