The Bar copper is undated and of uncertain origin. It has 13 parallel and unconnected bars on one side. On the other side is the large roman-letter USA monogram. The design is virtually identical to that used on a Continental Army uniform button.
The significance of the design is clearly defined by its extreme simplicity. The separate 13 states (bars) unite into a single entity as symbolized by the interlocking letters (USA).
This piece is believed to have first circulated in New York during November 1785, and may have been made in England.
John Adams Bolen (1826–1907), a numismatist and a master diesinker in Springfield, Massachusetts, struck copies of the Bar copper around 1862. On these copies, the letter A passes under, instead of over, the S. Bolen’s intent was not to deceive, and he advertised his copies plainly as reproductions. But his skills were such that W. Elliot Woodward, a leading auctioneer of tokens and medals in the 1860s, vacillated between selling Bolen’s copies and describing them as “dangerous counterfeits.” Bolen copies of the Bar copper are highly collectible in their own right, but they are less valuable than the originals.
