Uncertainty about the future during the Civil War led to widespread hoarding of coins, so Congress authorized the printing of fractional currency notes (with values less than a dollar) from 1862 to 1876. You can now get a two-piece set of this historic fractional currency, including a 10¢ note and a 25¢ note. These authentic mementos of the Civil War-era are in great demand among numismatic and historical collectors alike.
