"Paper money, that barometer of public faith, issued by both Congress and the states, was practically worthless. Businessmen insisted ruthlessly on 'hard money' for every commodity and every army supply. Ironically, even the counterfeiters who were rife were making better money than was the Congress. In February, 1778, newspapers published a warning against counterfeit thirty dollar bills. They were 'easily discovered,' the public was informed, because they were printed on better paper and the engraving was of finer quality than that of legal tender. The easiest way to spot one of the bogus bills, however, was to note that on it Philadelphia was spelled correctly, while on the genuine note it read, 'Philadelpkia.'" Scheer and Rankin, 1957, p. 303
