$1 Note

In order to finance the Civil War, Congress authorizes the U.S. Department of the Treasury to issue non-interest-bearing Demand Notes. These notes earn the nickname “greenbacks” because of their color. All U.S. currency issued since 1861 remains valid and redeemable at full face value.

Congress authorizes a new class of currency, known as “United States notes,” or “Legal Tender notes.” These notes are characterized by a red seal and serial number. They continue to circulate until 1971.
 

By 1862, the Demand Notes incorporate fine-line engraving, intricate geometric lathe work patterns, a U.S. Department of the Treasury seal, and engraved signatures to aid in counterfeit deterrence. To this day, U.S. currency continues to add features to deter counterfeiting.

The Bureau of Engraving and Printing begins engraving and printing the faces and seals of U.S. banknotes. Before this, U.S. banknotes were produced by private banknote companies and then sent to the Bureau of Engraving and Printing for sealing, trimming, and cutting.

Legislation mandates that all banknotes and other securities containing portraits include the name of the individual below the portrait. This is why you see names below the portraits on banknotes to this day.

The Federal Reserve Act of 1913 establishes the Federal Reserve as the nation’s central bank and provides for a national banking system that is more responsive to the fluctuating financial needs of the country. The Federal Reserve Board issues new currency called Federal Reserve notes.

The appearance of U.S. banknotes changes greatly in 1929. In an effort to lower manufacturing costs, all Federal Reserve notes are made about 30 percent smaller—measuring 6.14 x 2.61 inches, rather than 7.375 x 3.125 inches. In addition, standardized designs are instituted for each denomination, decreasing the number of designs in circulation and making it easier for the public to distinguish between genuine and counterfeit notes.

Following a 1955 law requiring “In God We Trust” on all currency, the motto first appears on banknotes on series 1957 $1 silver certificates, then on 1963 series Federal Reserve notes.

Because United States notes no longer served any function not already adequately met by Federal Reserve notes, their issuance was discontinued and, beginning in 1971, no new United States notes were placed into circulation.
