Standish Barry, of Baltimore, circulated a silver threepence in 1790. He was a watch and clockmaker, an engraver, and, later, a silversmith. The tokens are believed to have been an advertising venture at a time when small change was scarce. The precise date on this piece may indicate that Barry intended to commemorate Independence Day, but there are no records to prove this. The head on the obverse is probably that of James Calhoun, who was active in Baltimore politics in the 1790s. The legend BALTIMORE TOWN JULY 4, 90, appears in the border. An enigmatic gold doubloon is also attributed to Barry.
