The Nova Constellatio coin was minted in 1785 as a pattern piece for a proposed national currency in the early United States. It was made of copper and featured designs that symbolized the emerging nation, including a depiction of a sun rising over a group of stars. The coin is considered one of the first coins minted in the U.S. and represents the early efforts to establish a cohesive monetary system. Its rarity and historical significance make it a highly sought-after collectible among numismatists.
