In the first half of the 19th century, for example, the Midwest was so short of authentic banknotes that people knowingly accepted counterfeit ones. “This was a region that needed money,” Mihm writes, “and counterfeiters provided it.”

When $100,000 of Bank of Missouri notes were found to be counterfeit, an avenging group of miners chased the counterfeiter all the way to New York.
