When coins disappeared from everyday trade

During the Civil War, uncertainty disrupted the ordinary flow of money. People held on to gold and silver coins rather than spend them, leaving shops short of the small change needed for routine purchases. A customer might have paper money for a larger payment, while a shopkeeper had no coins to return the difference.

Paper took over the smallest payments

The workaround was to print money in amounts too small for the usual banknotes. Three-, five-, and ten-cent notes could settle a minor purchase or make change without requiring a scarce metal coin. The federal government issued fractional-currency notes, while local and private issuers also produced small-denomination paper money. “Shinplaster” was a mocking nickname for these flimsy notes, not the formal name of one single issue.

Their usefulness depended less on the paper itself than on whether people expected others to accept it. A note that worked at nearby shops could keep transactions moving even when coins were hard to find; one that lacked trust was little help. The arrangement was a practical stopgap, but it also made a shortage of metal visible in the most ordinary way: in the change a customer could not get back.
