What is U.S. fractional currency, sometimes called stamp money?
Before, during, and after the Civil War, the US was always short on silver money and small copper change, so it printed paper money with denominations of less than one dollar. These are much smaller than other U.S. paper money and are more affordable than the larger notes of that era. The denominations available are 3, 5, 10, 15, 25, and 50 cents. At the time, the government promoted and claimed it was created to purchase stamps for our new cross country mail service first by Pony Express and then trains. This is another highly collected field that has had good appreciation over the last 10 years.
