5-cent US postal currency, by United States Postal Service, 1862
Five-cent US Postal Currency, first issue, featuring Thomas Jefferson. Gold, silver and copper coins were hoarded at the start of the Civil War and postage stamps became a popular form of currency; however the adhesive back was a serious impediment. On July 17, 1862, Congress authorized printing of Postal Currency notes in the denominations of 5, 10, 25 and 50 cents. These notes could be redeemed for postage stamps or for a US bank note in the amount of five dollars or more. The Postal Currency was succeeded by Fractional Currency in 1863.
