Frequently Asked Questions

Why were New Jersey Coppers minted between 1786 and 1788?

Following the Revolutionary War, the state of New Jersey was flooded with lightweight, worn, and counterfeit British coppers. On June 1, 1786, the New Jersey Assembly passed an act authorizing the coinage of three million copper pieces to establish a stable local currency and provide clean small change for citizens.

What does 'NOVA CAESAREA' mean on the coin?

'Nova Caesarea' is Latin for 'New Jersey'. The name honors Sir George Carteret, who had served as governor of the Isle of Jersey in the English Channel (historically known in Roman times as Caesarea).

What does the obverse horse's head and plow represent?

The design was adapted directly from the Great Seal of New Jersey, designed by Pierre Eugene du Simitiere in 1777. The horse's head symbolizes agricultural strength, speed, and defense, while the horse-drawn plow symbolizes the fertile farmland and agricultural backbone of the Garden State.

What is the historical significance of 'E PLURIBUS UNUM' on the reverse?

New Jersey was the very first regular coinage in America to feature the national motto 'E PLURIBUS UNUM' ('Out of Many, One'). Placed above a heraldic Union shield with 13 vertical stripes, it symbolized New Jersey's unwavering dedication to the newly unified United States.

Who were the minters of the New Jersey coppers?

Coinage was carried out by Walter Mould, Thomas Goadsby, and Albion Cox. Because of personal squabbles, they split into two separate mint houses: Goadsby and Cox operated at the Rahway Mint, while Mould established his own facility at the Morristown Mint.

What are the 'Camel Head' and 'Serpent Head' varieties?

Numismatists use the classification system established by Dr. Edward Maris in 1881. In certain dies, the engraver carved the horse's neck with unusual curves: on Maris 56-n, the neck has an exaggerated hump resembling a camel ('Camel Head'); on Maris 54-k, the neck is long and curved like a serpent ('Serpent Head').

What is the 'Running Fox' mintmark on the 1788 variety?

On certain 1788 New Jersey coppers struck at Walter Mould's Morristown mint, a tiny outline of a running fox appears as a privy mark in the legend beneath the plow. This running fox is one of the most famous and beloved colonial numismatic markers.
