Postal Savings stamps offered the ordinary citizen a way to save money incrementally, a little bit at a time, through the Postal Savings System.
These stamps were issued by the U.S. Post Office Department between 1911 and 1941. They were available in 1911 in 10-cent denominations, either as stamps or as a stamp imprint on a card to which other stamps could be added. Issues in 1940 and 1941 existed in denominations of 10-cent to 5-dollar.
The stamps were redeemable in the form of credits to postal savings accounts. The Postal Savings System was discontinued March 28, 1966.
